This publication is a technical and practical guide for soil acidification in commercial fields. It explains the soil chemistry involved, how to determine whether pH adjustment is feasible, and methods for acidifying soil. This guide is divided into five sections:
• Understanding soil pH
• The problem—iron chlorosis
• Causes...
Accumulation of excessive salt in irrigated soils can reduce crop yields, reduce the effectiveness of irrigation, ruin soil structure, and affect other soil properties. This publication is designed to help you evaluate the kind and amount of salts present in soils and to select management alternatives. This publication describes the...
This publication focuses on using water analyses to choose appropriate water treatment and water management practices for irrigated agriculture. It will help determine:
• What tests are needed to characterize water quality
• How to collect water samples
• How to interpret analytical data from a laboratory
• How to...
This publication focuses on how to design a soil nutrient monitoring strategy that fits today’s requirements for record keeping and increased accuracy in managing nitrogen (N), phosphorus (P), and other nutrients. We advocate the use of management units or zones for soil testing and nutrient application. To measure a real...
Phosphorus is an essential element for growth and reproduction of plants and animals. Agricultural enterprises often provide supplemental P to enhance plant and animal performance. Supplemental P inputs are provided in the form of fertilizer or manure for crops, and in the form of feed additives for animals.
