The term adobe does not mean any particular kind of soil. It is applied locally to clay and clay-loam soils indiscriminately. It generally signifies the heaviest, stickiest, crackingest soil in the vicinity. Most plants will grow well on heavy soils if they are kept from getting too dry and too full of water. This is done by using plenty of stable manure and other coarse stuff to make the soil more friable, which favors aeration, drainage, root extension and plant thrift. Friability is also promoted by the use of lime and by good tillage. The particular soil to which you refer is a black clay loam which can be improved in all the ways stated. It is a good soil for most flowers and vegetables if handled as suggested. You can get hints of what does best by studying your neighbors' earlier plantings. For a Reclaimed Swamp. I have land, formerly a pond which dried up in the summer months. It has been thoroughly drained now for several years. The land surrounding it is good fertile soil and produces good crops. On this piece, however, crops come up and look fairly well until about two inches high when they turn yellow and die. Mesquite grass and strawberries seem to be the only crops that will live, and they do not do at all well. Sorrel grows abundantly in the natural state. Apparently the reclaimed land which you speak of needs liming to overcome the acidity in the soil. Common builders' lime applied at the rate of 1000 pounds to the acre at the beginning of the rainy season ought to make the land much more productive and the soil, at the same time, more friable. Deep plowing with aeration will also help the land, and this treatment can begin at once if the soil is workable. Other additions of lime can be made later as they may be required to make the improvement permanent. Improving Uncovered Subsoil. What is the best treatment for spots that have been scraped in leveling for irrigation? The land can be improved by plowing deeply and turning in stable manure or green alfalfa or any other vegetable matter which may decay, rendering the soil rich in humus and more friable. Of course, it will take some time to accomplish this improvement, and it is necessary that there be moisture enough present to cause the material to decay in order that the improvement may be secured. Sand for Clay Soils. Will beach sand do adobe or clay soil any good? It gets hard at times and I thought that if I was to put beach sand in the ground the salt in the sand would do the ground harm.
