Measuring and managing soil organic matter
projectblue.blob.core.windows.netOrganic matter adds to soil fertility and overall soil health by enhancing the physical, chemical and biological properties of soil (Figure 2): Fresh plant residues fuel biological life in soil The amount of active decomposing organic matter in soil has a large impact on biological properties, nutrient cycling and soil structure
Irrigation salinity – causes and impacts
www.dpi.nsw.gov.aumanagement practices, varieties and soil fertility. Effect of waterlogging on salinity tolerance Waterlogging exacerbates the effect of salinity. Waterlogged plant roots are unable to exclude sodium and chloride due to the increased rates of transport of these ions, and concentrations in the plant shoot increase. Poor aeration also affects soil

SOILS, SOIL CHARACTERISTICS AND SOIL MANAGEMENT
www.agronomy.k-state.eduThere are 17 different nutrient elements that are essential for plant growth; of these, 14 are derived primarily from the soil. Soil also provides a place to store water and gives support for plant roots. The term, soil profile, is used to describe a vertical cross-section of the soil from its surface down into the parent rock or earth materials
Save and grow: Cassava - Food and Agriculture Organization
www.fao.orgimprove soil fertility with other “Save and Grow” measures. Intercropping grain legumes, and mulching the residues of legumes and native weeds, boosts root yields. When combined with fertilizer, both alley cropping with deep-rooting leguminous trees and the use of organic compost or farmyard manure produce higher crop yields and net incomes.
