Soil Testing and Plant Analysis Relationships for Irrigated Chile Production

Soil nitrate testing supports nitrogen management in irrigated annual crops

Soil nitrate (NO3) tests are an integral part of nutrient management in annual crops. They help growers make field-specific nitrogen (N) fertilization decisions, use N more efficiently and, if necessary, comply with California’s Irrigated Lands Regulatory Program, which requires an N management plan and an estimate of soil NO3 from most growers. As NO3 is easily leached into deeper soil layers ...

Soil-plant Relationships in the Tropics

As commonly defined, the tropics comprise that region of the earth lying between the Tropics of Cancer and Capricorn, constituting 38% of the larid surface (5 x 109 ha). The tropics may also be defined as those areas with mean temperatures greater than 18'C in all mor.ths of th. year. A third definition of the tropics specifies those areas with soils in which the tempera­ ture at a depth of 50 ...

Updated Guidelines for Soil Selection and Improvements for Irrigated Pecan Production: Alluvial Soils

Effects of Herbivory on Plant and Soil Characteristics; Allometric Relationships Change among Different Grazing Sites

Relationships between Soil Properties and Plant Diversity Indices (Case Study: Lashgardar Protected Rangeland, Malyer, Iran)

Plant diversity and vegetation distribution in an area are related to the soil physical and chemical properties. The knowledge of relationships between species diversityand soil parameteris essential for sustainable ecosystem management. This study was conducted to investigate the relationships between soil factors and species diversity indices in the protected rangelands of Lashgardar, Malayer...
