    Abstract: Biological monitoring is a sensitive indicator of soil ecological stress for early restoration. The addition of manure, such as sewage sludge (SS) to agricultural soil contributes to the enhancement of organic compounds. However, SS may contain toxic metals that potentially affect soil microbial growth and the enzymes they produce. Soil samples wer... Show More

    Abstract: The study was conducted in three Districts of Kagera Region, Tanzania to assess the inherent soil fertility status of farmers' fields. Thirty-three fields, located three to five km apart, were selected and soil samples (0 – 20 cm depth) were taken, mixed thoroughly, air-dried, ground, sieved through 2 mm sieve, and analyzed in the soil laboratory b...

    Abstract: Total number of countries and territories together are put at 235. Apparently, single blanket recommendation is not possible but one has to think of custom made and tailored solutions/policies-country and territory wise- and within country and territory wise. “How many are to be fed” and “How many are needed to feed” ? How much land needs to be ear... Show More

    Abstract: A survey was established to study the mobility of metals (Cr, Mo, Cu, and Zn) from soils amended with municipal sewage sludge (SS) into plants grown at three locations in Kentucky and compare metal concentrations in plants to their permissible standard limits. The field experiments were established at Meade, Adair, and Franklin Counties in Kentucky... Show More

    Abstract: Mulching facilitates more retention of soil moisture and helps in control of temperature fluctuations, improves physical, chemical and biological properties of soil. As, it adds nutrients to the soil and ultimately enhances the growth and yield of crops. The desired outcomes from raised-bed (wide ridge) are to: drain, aerate, prevent water logging,... Show More
