1. This Soils Bulletinprovides training material on composting for extension workers and teachers in countries in the tropics and subtropics. The objective is to promote the use of locally available organic materials to increase soil organic matter content for the improvement of soil fertility, and...
  2. The soil is much more than just a substrate that anchors crops in place. An ecologically balanced soil system is essential for maintaining nutritious, resilient crops. In Hands-On Agronomy, Neal Kinsey shows us how working with the soil to bring it into balance produces healthier crops with a...
  3. Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management,...
  4. Although it's not too easy, good garden soil has to be achieved and then maintained by a continuous program of good growing practices. The first step in this program is to find out the specific needs of your soil through soil testing. This booklet starts at the beginning and explains how to have...
  5. The purpose of this bulletin is to describe methods applied to utilize nitrogen-fixing systems in soil improvement and management and the consequent increases in crop yields obtainable by these methods. The rest of the integrated systems involved i.e. chemical and physcial manipulations, are...
  6. Keyline methods enable the rapid development of deep biologically fertile soil by converting subsoil into living topsoil. Keyline pattern cultivation enables the rapid flood irrigation of undulating land without terracing. Incidental results are the healing of soil erosion, bio-adsorption of...
  7. 1/1/1978 This publication discusses the different kinds of soils and how to improve and care for it.
  8. Cropping systems, as well as timing, method of application and forms of fertilizer, can influence fertilizer efficiency. Although there are many factors which cause various practices to have different relative importance in different areas, the importance of having an actively growing root system...
  9. The Soul of Soil explains how soil organisms supply plants with the necessary nutrients at the right time, in the right form, and in the right amount. The goal of ecological soil management is to enhance conditions for the billions of microbes found in every gram of healthy soil, without reliance...
