The study was aimed at assessing the fertility status of soils with special emphasis on cation “concepts” and related physico-chemical variables as decision-support tools in making fertilizer recommendations. Thirty six soil samples collected from three representative locations,...

Sulfur (S) deficiency is becoming one of the soil health challenges in the Ethiopian crop production systems. However, visual identification of its deficiency, especially in cereals is difficult, because the symptoms are nearly identical with those of nitrogen. Hence, deficiency...

Field survey was conducted in Arsi(Ar), East Shewa(ES) and Oromia Liuu(OL) zones in 2012-15 cropping seasons, aimed at assessing sulfur(S) status of soils through plant analysis. The general information on land-use, soil types, were collected using semi-structured questionnaire t...

Six on-farm experiments were conducted in 2013/2014 seasons, in the Central Highlands (CHLs) of Ethiopia, with the main aim of estimating optimum sulfur rate for wheat. The treatments were, 4-levels of S(S0 =0, S1 =5, S2 =10, and S3 =20 kg S/ha); 2-levels of N(N0 =0, N =N1 =69 kg...

Eighteen explorative field experiments were conducted in 2012/2013 seasons in three representative areas in central highlands of Ethiopia, to evaluate the effects of sulfur (S) vis-à-vis nitrogen (N) and phosphorous (P) on wheat. Furthermore, an assessment was made on the status...

Using high-analysis fertilizers lacking adventitious sulfur (S), coupled with traditional cropping-systems that mine S from native soil, leads to S deficiency. However, under field conditions, S deficiency symptoms are not easily identifiable in cereals, because they are mistaken...
