What To Do If Your Soil is Too Alkaline

图片
In A Nutshell Your best option is to add organic matter and grow plants that do well in alkaline soils. The Whole Story Technically, all soils with a pH higher than 7.0 are alkaline, or "sweet," but most garden plants tolerate a pH up to about 7.5. Alkaline soils are generally composed of basic (high pH) parent materials such as limestone (calcium carbonate). High-pH soils are more prevalent in arid climates, because rainfall does not leach the calcium and other basic materials out of the soil. Soil pH affects nutrient availability for plants, and in soils with a pH over 7.8, iron, zinc, and phosphorus deficiencies are common. Lowering soil pH is a slow and challenging process. "The truth is, lowering soil pH is hard, because the limestone in the soil continually dissolves," says Jessica Davis, Ph.D., a professor of soil science at Colorado State University. Davis recommends getting your soil tested to determine its pH, lime content, soil texture, and...

Soil amendments Part I

Soil amendments are materials which are worked into the soil to enhance the soil’s properties.  Examples would include organic matter such as compost, manure, bone meal or leaf mold,  as well as synthetic fertilizers. There are several reasons soil amendments might be recommended for your garden or lawn: 1) Often soil is low in organic matter, necessary for the structure, water retention and life of your soil.  2) You might also add amendments to alter the soil's pH.  3) Amendments are also excellent for lightening clay or rocky soil and adding substance to sandy soils.
