The chemical properties of the study area as in (Figs. 8–19) shows that EC is ranged from 0.1 to 0.31 d Sm-1 in salinity
class low and the nature of the soil is normal. pH shows that the soil difference between acidic, neutral, and alkaline soil
and this clear in the area as it is suffer from moderate water erosion. Acidic classes found in high land, neutral soil found
in mid portions of low land and alkaline soil found in low land as a result of water erosion. Organic carbon (%) shows that
soil is different between low, medium and high. Low classes of organic carbon found in high land, medium organic carbon
content in soil found in mid portions of low land and high content in soil found in low land and the highest amount found in
forest area. Low content of Organic matter refers to the high rate of organic decomposition because of high temperature
of the climate and less application of organic residue. Nitrogen shows that the study area has low nitrogen content as result of low organic matter in soil. Available phosphorous shows that the study area has the three ratings low, medium and high phosphorous content in soil. Small area has low content and remains area between high and medium content of phosphorous. Micronutrients show that most the study area has Iron content under critical level (2.5–4.5 ppm) and very less occupied area with iron within the critical level (2.5–4.5 ppm). Eastern part of the agriculture area of Chamarajanagar district has manganese content above the critical limits 2.0 ppm but western part is under the critical limits. Copper is higher than the critical level 2.0 ppm in most of the area and small part of the district is under the critical level. Zinc is lower the critical level 0.6 ppm in most of the area and small part of the district is above the critical level 0.6 ppm.
