Soil test results will state how much lime to apply your garden, but in the absence of a recommendation, apply dolomite lime at the rate of 1 to 2 pounds per 100 square feet, and mix it 6 inches deep into the soil with a spade or rototiller. Most vegetable plants prefer to grow in a slightly acidic soil and won’t produce well if the soil is alkaline. The lime that gardeners add to their soil is limestone that’s been quarried and crushed into fine particles. While a gardener adds fertilizer to the soil to nourish plants and add nutrients to the soil, lime neutralizes the soil by counteracting acids. The symbol \"pH\" and the figures accompanying it are used to express the degree of soil acidity. More isn’t better when it comes to maintaining a healthy balance of nutrients in garden soil. Lime takes weeks or months to become active in soil, so you must time your application with that fact in mind. Preparing a soil sample for a soil test is straightforward and should be completed about six months before planting your garden. Place this sample in a clean bucket. As well as the calcium in lime, vegetables also require nitrogen, potassium and phosphorus to grow healthily. If you don't have soil test results, it is generally safe to apply lime at a rate of 1 cup for each 50 square feet of garden. When nothing is growing in a vegetable garden, the soil could be lacking in any of these nutrients. Rake the lime into the soil.

To make watering your garden convenient, set up a drip irrigation system in early spring before planting or sowing your vegetables. The issue with lime is that unless your soil is way down in the pH 5 range adding lime can skew you way into the alkaline range. Conversely, if you dig up a tablespoon of dry soil and drip several drops of vinegar onto it, any fizzing indicates the pH of the soil is above 7.5 and therefore is alkaline. If you apply too much pH in an area that does not need it, then other nutrients will become tied up and crops will not be able to grow healthy in the vegetable garden. Soils that are even slightly too acidic won't produce good quality tomatoes and will bind calcium and magnesium into the soil where plants cannot access it. University of California Agriculture and Natural Resources: Fertilizer, Mulch or Amendment? You do not want to lime when you have crops in the ground as the lime may well damage the crops Since brassicas like both high amounts of nitrogen & humus as well as a high pH, manure in the autumn for them and lime in the early spring, Vegetables need air in the soil around their roots, and if the soil is regularly soggy, their roots will drown. Dolomitic lime and clacium carbonate are great when used with calsium sulphate, here in brasil we used to eliminate Al but we saw that besides giving a better ratio of calcium and Mg it also can take Ca to lower levels since de dolomitic lime and CaCO3 do not move easely in the soil.Obs:if you use CaSO4 with potasim fertilizers insted of CaCo3 you can move some K to lowers levels of the soil. An overall picture of what over-liming actually does to a soil can be seen by taking a soil sample prior to the use of the lime and following up each year for the next three years.
