An investigation was carried out at College of Agriculture, Vellayani, Thiruvananthapuram, Kerala to develop the nutrient management strategies for restoring the soil fertility of post flood soils of AEU 3 (Onattukara sandy plain) of Kerala. Rice- based cropping system is the major cropping system in low land and coconut based cropping system is predominant in uplands in AEU 3. The overall nutrient status of post flood soils of AEU 3 indicated that the soil was very strongly acidic with low to medium status of organic carbon and potassium and medium to high level of phosphorus. Application of lime based on soil test has to be followed. Sustained crop productivity and land quality can be ensured with the use of recommended levels of organic manures. In the case of N, application rate can be increased up to 125 % in low status areas depending on the organic C status. High levels of available P can have negative influence on uptake of other nutrients especially calcium magnesium and zinc. In areas where available P is very high the application can be either skipped for two years or reduced to 25-50% of the recommended dose depending upon the soil status and crop needs for all the crops. In the areas where K content was medium the 100 % recommended dose can be given and it can be increased to 125 % where K is low. Nitrogen and potassium can be applied in splits to reduce the leaching losses. Soil test based application of manures and fertilizers will lead to saving of fertilizers to the extent of 50-90%. This will help the farmers not only to enhance their income but also to restore the soil fertility of post-flood soils and it will in turn sustain soil health and protect human health.
