is caliche acidic or alkaline

Why is caliche bad for gardening?

The caliche’s alkalinity can prevent plants from being able to take in the nutrients they need to survive. Make your soil more acidic to offset the challenges of gardening in caliche. Acidifying soil that contains caliche reduces the soil’s pH level and makes it much easier to successfully grow plants with the soil you have.

What is caliche soil?

Caliche (pronounced as “ka-lee-chee”) is a notoriously difficult type of soil to work with that develops when lime, also called calcium carbonate, builds up in the ground. Gardeners working with caliche will soon discover that, without amending the soil or otherwise improving it, it’s practically impossible to grow anything in caliche.

What is a caliche layer made of?

It generally consists of carbonates in semiarid regions—in arid regions, less-soluble minerals form caliche layers after all the carbonates have been leached from the soil. The deposited calcium carbonate accumulates—first forming grains, then small clumps, then a discernible layer, and finally, a thicker, solid bed.

How does caliche form?

Caliche forms where annual precipitation is less than 65 centimeters (26 in) per year and the mean annual temperature exceeds 5 °C (41 °F). Higher rainfall leaches excess calcium completely from the soil, while in very arid climates, rainfall is inadequate to leach calcium at all and only thin surface layers of calcite are formed. Plant roots play an important role in caliche formation, by releasing large amounts of carbon dioxide into the A horizon of the soil. Carbon dioxide levels here can exceed 15 times normal atmospheric values. This allows calcium carbonate to dissolve as bicarbonate. Where rainfall is adequate but not excessive, the calcium bicarbonate is carried down into the B horizon. Here there is less biological activity, the carbon dioxide level is much lower, and the bicarbonate reverts to insoluble carbonate. A mixture of calcium carbonate and clay particles accumulates, first forming grains, then small clumps, then a discernible layer, and finally, a thicker, solid bed. As the caliche layer forms, the layer gradually becomes deeper, and eventually moves into the parent material, which lies under the upper soil horizons.

Why are caliche beds bad for agriculture?

First, an impermeable caliche layer prevents water from draining properly, which can keep roots from getting enough oxygen. Salts can also build up in the soil due to the lack of drainage. Both of these situations are detrimental to plant growth.

How to find your exact location on a soil survey?

The soil surveys do take a little navigating. Pick your state, pick your county, wait for pdf to load. In the pdf should be a "index to map sheets" section where you can locate your exact location visually. There isn't a lot of additional information on these maps except the soil survey data so you may need to compare the soil survey map with another map in order to find your exact location. I was able to find my exact location by comparing a "mapquest" generated map (use the satellite view) of my location to the soil survey maps. Take your time comparing the maps and make sure you have the right location. Once you see the USDA soil survey map I think you'll understand.

Why is caliche bad for plants?

Caliche is terrible for plants for three reasons: (1) Plant roots cannot penetrate it, so they become root restricted. (2) Water can’t drain through it, so roots are suffocated. (3) Its alkaline nature can make several essential micronutrients (phosphorus, iron, boron, zinc, and manganese) unavailable to plants. Gardeners with alkaline soil such as caliche need to be on the lookout for signs of nutrient deficiency in their plants.

How to break up caliche?

This means breaking it up with a mattock or rock bar, ripping it with a plow or tiller, removing it with a jackhammer (I’m not kidding), or even using an auger to dig planting holes for trees and shrubs. These methods may sound extreme, but if you’ve dealt with caliche before, you know that they aren’t! The key here is to tear an opening in the caliche layer that’s big enough to provide a space for the plants’ roots to penetrate to the better soil below. If the hole that you’ve dug for a plant doesn’t fully penetrate the caliche layer, you can use a drill with a long masonry bit (the length of the bit will depend on the depth of your caliche layer) to make a couple of holes down deep through your planting hole. This is the step that we all wish wasn’t necessary for gardening in caliche because it is the most work, but it’s necessary. The only time you may get away with not doing this is if your caliche layer is deep in your soil, but if that’s the case then you are likely not looking for ways to remedy it.
