Long term use of Maresha plow, a conventional plow pulled by oxen, has resulted in the formation of a restrictive layer thereby limiting water movement and aeration as well as root zone penetration in the soil profile. Several studies have shown that improved tillage practices can positively affe...
Soil carbon enhancing practices (SCEPs) have been proven to be low-cost solutions in enhancing agricultural productivity and alleviate the detrimental effects of climate change. These practices can be adopted as complementary or as substitute practices due to their associated ecological benefits ...
In the Ecuadorian Cordillera, the hardened volcanic ashes (cangahuas) account for 15% of the cultivated area. The soil resulting from the fragmentation of these materials, generally by heavy machinery, shows an apparent stable millimetric structure. However, this new structure is highly susceptib...
Discusses the results of the measurement of environmental changes in grazed ecosystems with reference to correlated changes in livestock management in Kenya; includes techniques used to measure the changes, and proposed methods; presents data on a case study at a group ranch located in western Ke...
Soil erosion is a serious threat of increasing dimensions and tends to blunt efforts to counter global population growth with increased and sustainable agricultural production. Especially the tropics are vulnerable because of the circumstantial convergence of intense climatic regimes, frequently ...
