Physical and Chemical Properties. The study has revealed that most of the soils in Chikwawa and Ntcheu districts are xxxxx xxxx as evidenced by the percentage proportions of silt and clay. The soils from Chikwawa were slightly acidic to alkaline with their pH ranging from 6.85 to 8.61 while those from Ntcheu were mostly acidic with pH levels ranging from 4.91 to 6.48. The study has also revealed that there is no significant variation (Fpr = 0.78) in the soil physical properties within each sampled district. For example, the distribution of clay in Ntcheu did not vary significantly (Fpr. = 0.91) from sites to sites. This shows that generally the soils are homogenous and that the significant variation (Fpr <0.42) in soil chemistry is attributed to the application of agricultural fertilizers and pesticide chemicals rather than the parent rock’s properties from which the soils were formed. Therefore, it is clear that different fields are being treated differently by different farmers. This agrees with the household surveys in the area which revealed that some farmers were not using chemicals pesticides and agricultural fertilizers, while others were heavily applying the two. It is therefore expected that from such fields, the soil chemistry will be different. The study also deduced that the most prevalent agricultural pollutants are pesticide residues and nutrient fertilizers. Results of actual levels of pestcides found in produce are underway. It is envisaged that the soil and water ecosystems are polluted via drainage and irrigation of the field’s water overflow of water as well as careless handling of chemicals by farmers in some cases.
