Organic materials, the combined products of different animal and plant sources, play vital roles in agricultural crop production systems. They are more environmental friendly than inorganic fertilizers and added many values to soil and crop production, economically. They sustain and restore soil inherent properties, enhance soil biological activities and potentially increase crop yields, which are safe for human... Read more.

Vermicomposting is a process where worms are used to transform organic waste products into fertilizers for agricultural use and as soil amendments to improve soil health. Vermicompost is used in agriculture as both an organic fertilizer and a soil amendment due to its large biological component and abundant nutrient concentrations, in particular nitrogen (N). Vermicomposts promote soil microbial biodiversity by... Read more.

Soil thermal parameters are mainly inputs for models of soil heat flux. Mathematical models are important tool for predicting the soil heat and water transfer, depending on some fundamentals of soil physical properties. Soil moisture is one of the soil physical properties that have a great effect on thermal parameters. The aim of the work is to describe the behavior of soil thermal parameters under different values of... Read more.

This study was carried out to assist in the formulation of conservation technologies for landscape sustained productivity in the Usambara Mountains, Tanzania. Conventional soil survey methods were used to develop a base map on which 55 soil profile pits were randomly located on representative landforms and land use mapping units. Soil samples were collected from topsoils for soil carbon analysis using the wet digestion... Read more.

Soil is one of the most essential natural resources. That is why soil fertility management is a major global concern. The current study in Delta sub-watershed was conducted to assess farmer’s perception on soil fertility status of small holder farming system under different land uses, Enset (Ensete ventricosum) farm, grazing and agricultural land. Both secondary and primary data were collected through direct field... Read more.

Oxisols are one of the major soils of Malawi and they are high in P sorption. Conservation agriculture has been practiced on this soil for some years now but soil management effects on P sorption and external P requirement (EPR) of Oxisols in Malawi have not, however, been determined. Soil management effects on P sorption and EPR of Oxisols in Malawi were therefore determined in the present study. The effects studied... Read more.

Selenium (Se) is an essential micronutrient for humans and other animals. Its deficiency in food can cause cancer, cardiovascular and other diseases in humans. In high concentrations, Se is toxic for humans, animals and plants. The bioavailability of Se in soils largely determines the Se level in food, feed and therefore throughout the nutrition chain. Selenium content in soils is highly variable. The objective of this... Read more.
