Phosphorus is one of the key factors that regulate soil fertility. Its deficiencies in soil are largely replenished by chemical fertilizers. The present study was aimed to isolate efficient phosphate solubilizing fungal strains from Eisenia fetida vermicompost. Out of total 30 fungal strains the most efficient phosphate solubilizing one was Emericella (Aspergillus) nidulans V1 (MTCC 11044), ide...

Plants inoculated with arbuscular mycorrhizal (AM) fungi utilize more soluble phosphorus from soil mineral phosphate than noninoculated plants. However, there is no information on the response of soil microflora to mineral phosphate weathering by AM fungi and, in particular, on the catabolic diversity of soil microbial communities. The AM fungus, Glomus intraradices was examined for (i) its eff...

The begining of phosphatic deposits study was dated around 1963 through the survey developed at Bahia Tongoy, and later on at Pachingo in 1989. In this article, a synthesis of the main geological, physico-chemical, and agronomic features of these materials is presented, remarking some of these properties, and agronomical applications obtained after the accomplished research. Location of deposit...

Tilemsi rock phosphate (TRP) of Mali is one of the most promising rock phosphate in West Africa for soil fertilization, but it is little used because of its insoluble form. The main objective of this study is to investigate TRP effects on rhizobia associated with the multipurpose leguminous tree Sesbania sesban grown on a sandy soil, poor in phosphorus and not sterilised. The experiment include...

Food production requires application of fertilizers containing phosphorus, nitrogen and potassium on agricultural fields in order to sustain crop yields. However modern agriculture is dependent on phosphorus derived from phosphate rock, which is a non-renewable resource and current global reserves may be depleted in 50–100 years. While phosphorus demand is projected to increase, the expected gl...

Agrogeology is a relatively new applied, problem-solving, interdisciplinary earth and agricultural science that aims at improving agricultural production using agromineral resources. There are two aspects of agrogeology: 1. The influence of parent material on soil development and soil fertility, and 2. The beneficial application of rocks and minerals to enhance soil fertility and crop productiv...
