“…Other studies suggested that soil acidification influenced crop yield by its effects on N mineralization, soil microbial activity, and root growth (Curtin et al, 1998;Umiker et al, 2009;Haling et al, 2011). These soil properties were not measured in this study.…”

Soil acidifi cation has become a major environmental challenge for crop production in the inland Pacifi c Northwest (iPNW). We evaluated the eff ects of tillage and N-fertilizer management on soil pH, soil organic carbon (SOC), soil N, and crop yields from 1995 through 2010 in an ongoing long-term experiment in eastern Oregon. Tillage systems included moldboard plow (MP), disk plow (DP), and subsurface sweep (SW) and N-fertilizer rates were 0, 45, 90, 135, 180 kg N ha -1 crop -1 in a dryland winter wheat (Triticum aestivum L.)-summer fallow (WW-SF) system. Soil pH, SOC, and N were monitored in 1995 and 2010, and crop yields were monitored every other year. Soil pH was lower in the higher N rate treatments. Long-term N fertilizer application increased soil acidity in 0-to 10-cm depth by 0.3, 0.2, and 0.3 units in MP, DP, and SW, respectively, for every 1000 kg N applied through ammonical N fertilizers. Soil pH was higher in DP than MP in 10-to 20-and 20-to 30-cm depth profi les. Th e SOC and N concentrations in the top 30-cm depth were lower in 2010 than in 1995 across all treatments. Wheat yield increased signifi cantly with increase in N rates from 0 to 90 kg N ha -1 crop -1 . Th ere were no further yield increases above 90 kg N ha -1 crop -1 . Soil acidifi cation, SOC and nutrient dynamics should be carefully monitored in cropping systems using ammonical N fertilizers, particularly under high rate of N application and reduced tillage.

Soil acidity problem is one of the bottlenecks to improve crop production in high rainfall regions of Ethiopia in general and in Gozamin District of Amhara region in particular. The aim of this study was to examine the effects of integrated use of lime, manure and mineral P fertilizer on acid soils for wheat production and status of residual soil P. The treatments were factorial combinations of lime, manure and P fertilizer which were laid down in a randomized complete block design with three replications. The field study was conducted on Dystric Nitisols in the 2011 and 2012 main cropping seasons at Enerata Kebele, Gozamin District. Lime application hastened early germination while plant height was enhanced by interaction of lime and P. Most parameters were significantly (p < 0.01) affected by two-way interactions while three-way interactions effect increased grain and straw yield at non-significant (p > 0.05) level. In these interactions lime rates were related in quadratic trend while manure and mineral P related linearly. The combined application of 5 t manure and 2.2 t ha -1 lime increased grain and straw yield by 279% and 187%, respectively over the control treatment through economical analysis result 515 Eth. birr ($28) ha -1 profit obtained due to additional yield obtained. Although all treatments residual soil P were categorized under very low status, it has strong positive correlation (r 2 = 0.79) with lime application. The present study showed the combined application of 5 t manure and 2.2 t ha -1 lime was found to be economical feasible to improve wheat yield and yield components and residual soil P of acidic soils of the study area.

“…Alteration in root length and number of roots causes an alteration in root dry weight. Alteration also occurs on root hair length and root hair density (Haling et al, 2011) that cause an alteration in root dry weight. In this study, root dry weight was not in line with root length and number of lateral roots, where root dry weight increased in Mn toxicity but equal to low pH (Table 2).…”

“…Number of lateral roots is very important, because its alteration can identify the tolerant genotype. Lateral root is also more important than primary root, because lateral root is more sensitive (Haling et al 2011). However, a difference was found between root length and number of lateral roots.…”

Abstract. Kuswantoro H. 2016. Differential response of roots growth of soybean germplasm under low pH and manganese toxicity. . Most of Indonesia dry land are covered by acid soil. The growth and development of the plant in this acid soil cope with low pH and micronutrients toxicity. The objective of this research was to study the response of root growth of soybean germplams to low pH and manganese toxicity. Nine soybean germplasm were treated in aquadest with pH 7 as control, aquadest with pH 4, and 75 ppm Mn with pH 4 in Seed Laboratory of Indonesian Legume and Tuber Crops Research Institute, Malang, Indonesia. Results showed that root length, number of lateral roots, root dry weight were lower in low pH and Mn toxicity than in the control. Shoot dry weight, hypocotyl length and epicotyl length were not influenced by low pH and Mn toxicity. Some genotypes showed increasing root length in low pH, and increasing number of lateral roots and root dry weight in Mn toxicity. Based on the acid soil adaptation index (ASAI) on root length, MLGG 0493 and MLGG 0496 showed the highest value index in three comparative conditions. The genotype of MLGG 0496 also showed the highest ASAI value on numbers of lateral root in three comparative conditions. MLGG 0494 achieved the highest ASAI value of root dry weight. However, the use of root dry weight as a criterion in soybean adaptation in low pH and Mn toxicity should be studied further because the tolerance is not just in increasing root dry weight as a result of root thickening.
