The effect of rock phosphate-enriched compost on the yield and phosphorus nutrition of rye grass

Article Abstract:

Indigenous low grade rock phosphates such as Mussoorie phosphate and Hyper phosphate can be used directly after composting with farm wastage for improved agricultural production without polluting the environment. Large amount of insoluble phosphorus is converted in to organic compounds during composting reducing the possibilities of phosphorous fixation. In the study no significant differences between effects of Mussoorie phosphate and Hyper phosphate were observed.

Erosion effects on soil moisture and corn yield on two soils at Mlingano, Tanzania

Article Abstract:

The impact of soil erosion on soil properties and corn yield for Tropeptic Haplustox and Ultic Haplustalf soils in Mligano, Tanzania are studied. Results show that erosion negatively affected degree days, soil organic carbon, available water capacity, moisture content and bulk density. These effects, in turn, decreased corn yields by 49% for Tropeptic Haplustox and 59% for Ultic Haplustalf soils.
