This means a tougher, longer lasting result. In addition to this, Dolomite has a lower solubility, making it resistant to dilute acid media, meaning it does not break down or erode nearly as fast as Limestone when subjected to the acid contents of rain and soil. Consequently, Dolomite requires higher temperatures before it starts decomposition, which makes it better for environments with varying temperatures; many outdoor walkways and structures use the stone as an outer or top layer.
In fact, studies have shown that Dolomite provides excellent binding materials for mortar and concrete as you can obtain dolomite lime and magnesium binder from it. There are numerous benefits to using these binding materials in concrete, one specifically being that it provides a great contact zone with organic natural fiber aggregate. Not only is it a great binder, but the fine and ultra-fine particles that are derived from it can act as a great micro-filler, which is an important component of concrete mixtures.
Filling micro voids is crucial, as this process creates a more dense microstructure, meaning an increase in impermeability to the elements. In addition to improving the impermeability of the structure, Dolomite has been tested in lightweight aggregate concrete in comparison to natural sand. In these tests, it was found that Dolomite provides the same mechanical properties and water impermeability in addition to compressive strength as the natural sad did; the incorporation of Dolomite by-products also improved the stability and workability of the mixes.
So when it comes to durability and longevity, Dolomite is definitely the winner. Water and acids take much longer to seep into the stone compared to its counterpart, Limestone.
Since water takes longer and is less likely to seep into cracks, this means more resistance to the usual breakdown caused by freezing and thawing cycles, resulting in a longer lasting, durable structure.
This is where choosing Dolomite instead of Limestone as your aggregate shows one of its biggest advantages. One of the benefits to using Dolomite over regular Limestone is its effectiveness in the agricultural industry. Due to the high concentration of magnesium in the stone, it is able to provide a highly effective, long lasting boost to nutrients in soil and balance the pH levels.
In addition to being able to neutralize the pH, the lime that is introduced helps encourage the growth of microorganisms, which contribute to plant health. The crystalline, porous structure of Dolomite also provides aeration to the soil, stimulating nitrogen production and absorption. This enrichment helps with both magnesium and potassium deficient plants, allowing them to flourish.
Additionally this boost can last between months, whereas regular Limestone would only last between months. While this article focuses mainly on the aggregate usage of the rock, many other vocations make use of the material. This material is highly useful, resilient, magnesium-rich, and most importantly, often times less expensive than regular Limestone. Pattison produces high quality ordovician dolomitic limestone Aggregates and silica proppants. Our Clayton IA, quarry contains multiple limestone ledges yielding material with a variety of properties that meet various requirements.
Driving Innovation, Creating Value. If you choose a liming material low in magnesium, be careful to avoid magnesium deficiencies. High calcium applications alone can decrease soil and plant magnesium levels. If the soil is acid and originally has a low magnesium content, adding a calcitic low magnesium liming material or high rates of gypsum could induce a magnesium deficiency.

Most important would probably be to collect as much rainwater as you can in a cistern and save it for irrigation, plus mulch well in order to conserve water, so you can irrigate less.
Hi — I am a new reader of your site. I have almost completed rehabbing an old historical stone house quite large for 1 person, and only 29 years old at that. My savings are almost tapped, but I work at Wall Street as an Actuary.
My home sits almost at the center of a 25 acre lot. There is also a carriage house, and a huge [ and i mean huge ] barn and along the periphery — a lake which unfortunately overflowed by storm Irene.
I have not really done much with the entire surroundings, except for clearing most of the dead trees and cleared some of the shrubs — thanks to the University of Penn Arboretum Dept.
And it cost me an arm and a leg. My Dad is a civil-mechanical-civil Engineer and an architect. He tells me both the carriage house and the barn are solid. I want to complete the landscaping of the entire 25 acre with little help from Mom and Dad. Where do I start? I travel back and forth to China — I do not have that kind of time oversee the project.
Wow, big project. I would pay a permaculture designer to come in and walk the property and give you advice. On 25 acres, I would definitely go for more of a natural look than a manicured look.
Lack of blooms means lack of energy and nutrition, which can be for any number of reasons. Improving the soil organic matter content, microbial diversity and nutrient balance along with proper watering and other basics should help. I was researching how to change Hydrangeas to a deeper pink. Dolomitic lime is suggested. Your hydrangeas will find the color they want to be. Adding a small amount of dolomite right around the based of the hydrangeas will not significantly hurt the surrounding grass, but over time, it may compact the soil around the hydrangea and invite plant predators to come in and dine.
We have a large family garden with all kinds of vegetables in it. The new leaves on the zucchini and cucumbers are beginning to yellow. Is this a problem with the dolomite? I read in a garden book this could be because of too much magnesium. What do you think and how would you try and fix this? In the long run, the soil needs to be tested and balanced, which is a big topic that I cover in month 2 of the Academy.
In March I added about 50lbs of dolomitic lime to my square foot vegtable garden to correct the ph,, thinking lime was lime.
The garden has mostly hot peppers. Most were started by seed and were looking good. I put them in the garden and they imeaditly died. Even the peppers I bought from a green house. The garlic, potatos, carrots look ok so far, do you think the mg might have killed them? Is there any way to undo what I may have done?
Any help would be great. It has a slower effect on the soil. Hi, I read on line to add dolomitic lime to my soil, because my zuchinni was turning yellow on the ends before they mature. My soil is really almost clay. Can I put a little around the base of the plant.
Physiological diseases in plants are generally more complicated than just adding one or two minerals. I would instead focus on a broad spectrum fertilizer such as sea minerals or kelp, and definitely some good compost, and some effective microorganisms.
These all help to improve the health of the soil and plant from a more holistic perspective. If you want to balance your soil nutrients, do a soil test first through a good organic lab. Then you know what you need.
Your information is lacking facts. Why would you tell people liming their soil is bad without giving more information? It is not as clear cut as you make it out to be. You do not even address the K:Ca:Mg ratio that many plants want. That is an important factor considering how important Ca is to plants, and the synergistic effect the three elements have to one another.
Nor do you address that organic elements, especially those coming from rocks, but in general many, can and do have components that are undesirable for your health, such as flouride and even Polonium It is fascinating, when you actually are open to both sides of the equation, that water soluble fertilizers, typically being highly refined impurities being removed , can actually contain less undesired components than organics do.
I can appreciate your desire to inform people of common errors, of which over liming is one, but you make it sound so clear cut. I guess it depends if you want healthy soil or healthy plants. You should use it when a soil test indicates you need the calcium and magnesium.
Thanks again for you comments, Phil. Do you have any other suggestions? But it is a difficult plant to get rid of. Improve drainage, fertility balance, the soil food web, and pull pull pull for years to come. I live in the very lush and rainy willamette valley in Oregon. Every year until recently my tomaoto harvest has been poor and frustrating. When I planted my starts last year, I threw in a very small quarter cup helping of dolomite lime in each hole before planting.
The crop was incredible. The tomatoes were large, juicy, and perfect. Before this crop, I was afraid that I did not have the green thumb. Researching and understanding nutrient levels in soil definitely helped. I was not aware of the high magnesium levels in dolomite lime, but I can honestly say that I will continue to use it with my tomatoes and peppers.
I had more than I knew what to do with! I only used organic starts and organic fish fertilizer. Your soil must have needed magnesium and calcium. Great points you have shared in this post. Its really important. Thanks for sharing this post with us. I am surfing for something like this. Keep it up in future too. Do you have any recommendations as far as applying lime at planting or maybe not at all right now? But in terms of the actual fertilizing, you can do it after you plant. I just wanted to dump there potting soil and grow my garden!
As for a good fertilizer, kelp fertilizer is pretty easy to find. I use Earthboxes to grow veggies. Also the peat is very acidic and the pH needs to be raised. Does this seem correct? Most all plants need a lot of calcium. Calcitic lime is better than dolomite for that. The peat may or may not be acidic depending on what kind of peat it is. The lime is probably not a bad idea either. I have a paddock for my horses that is pH 5.
The number of buttercups is increasing these can be toxic for horses if forced to eat them through lack of grass not at that stage yet but want them gone!!
They were deficient in Selenium by blood tests as was the soil. I supplemented them with a proprietary product which contains selenium and vitamin E as an antioxidant and a spectrum of minerals. On second blood test the horses were too high in zinc which was tying up the copper…which they were slightly low in first time around.
I have reduced the supplement to reduce the zinc and thus not tie up the copper…also giving the horses a herbal copper blend and will blood test again in the autumn.
Any advice to get rid of the buttercups without harming the other grasses and plants would be appreciated…. Increasing pH will be a byproduct of balancing out soil fertility, but the pH number should not be managed directly. They will tell you exactly which nutrients you need to balance out your soil so that it favors grasses over weeds, balances the pH, and gives your plants and horses more nutrition in general.
But yes, lime is probably called for — not dolomite lime, you just want calcitic lime for the calcium. And then there will be other issues the soil lab will tell you about. How much dolomite lime and potassium should I use on two lavender plants? I am growing the plats in a large pot will I hope they will grow. I have been growing veggies in earth boxes. The directions always say to add one pound of dolamitic lime to the top inches of soil and work it in before re-planting…..
Did the lime cause this? I was thinking I needed to add more lime until reading this. Now I wonder if I was using too much? I use a very good potting mix in my boxes…. Dolomite probably makes more sense in potting mixes, although I still tend to go for calcitic lime. Phil, I stumbled onto your site. I am expanding a growing area for vegetables that is still very much a yard. My plan is to make boxes, drop cardboard in, cover with straw, then come a bit more with leaf mulch that I was able to get for free.
I plan to use blood meal, or at least I did until i read your other post on kelp, as I have had great success with gardens in the past. I would wait at least a year for everything to break down before you do a soil test.
I have a sq ft vegetable garden. I just got another soil test back from UMass listing a 5. CEC is Their recommendation for a target pH of 6. So, my question is, how can I increase pH without adding a significant amount of calcium or magnesium? That calcium base saturation is low, so I would add calcitic lime aka calcium carbonate , not dolomite.
I look at the base saturation percentages more than the absolute numbers. I just scrubbed the moss off my terrace with acid.
Too late I realized that I would have to wash it down and that was straight through my garden. I just washed it over and over to try and dilute the acid. Someone suggested I use dolomite lime , dig it into the soil and water it. Is this not going to do the garden more harm than good?
Any suggestions…. The terrace looks great but I fear for my garden. Nice piece on lime in general. Keep on Smiling…. But also have 3 questions, please. Thanking you in advance. There can be many reasons for lack of blooming, the most common being not enough sun, improper moisture, frost damage, too much fertilizer, too much or improper pruning, animal damage. Those are the main ones that come to mind. I plan to have a straw bale garden and I have a recipe of minerals to treat the bales with before planting seeds.
I am having trouble finding dolomite meal in powder form. I have cut down a 50 ft. I have fertilize it and last year added dolomite to the area. The grass is still very sparse and does not want to grow. What should I do other than make a flower garden where the tree was. Hi, just been searching online for dolomite, i have an olive tree that doesnt hold its flowers and falls off before it fruits…so i cant enjoy any olives from that tree, i been told by few ppl that its a male tree and i should cut it down.
But I recently got in contact with famous tv gardener that not to cut the tree at all and just add dolomite to it. It will fruit like u wouldnt believe and enjoy ur olives he said. Is this true? The surer solution is to test your soil and fertilize based on that soil test, and also to improve the soil biology.
Dolomite can often contain sodium, but it should only be 0. More sodium can change the salinity of your soil, which can kill many plants. Dolomite limestone is best used to change the acidity, or pH, of the soil.
Start with a soil pH test, which you can buy at garden centers, to determine the existing pH. Most plants do best with a pH of 6.
If your soil registers with a pH of 5. Some plants prefer acidic soils, where the pH is lower, so check on your specific plants' needs before adding the dolomite.
