1. Identifying variations across the farm plot

• Grid Soil Sampling: You need to divide your plot of land into imaginary systematic grids; collect soil samples from each grid and get them tested. It would help you decide which crops to grow and develop a map (Soil Survey Map) of the specific manure and water requirements for each grid.
• Yield Map: You need to divide your plot of land into imaginary systematic grids according to the yield patterns that you have observed. Identify the highest and lowest yielding sections. This along with the soil test result from above samples would let you calculate optimum input to be applied (manure, water etc) for higher yields.
• Crop Scouting: You need to carry out regular monitoring of field crops and look out pest infections during the growing season. It helps you identify nature of pests, the growth rate, the amount of crops infected. This would help you adopt the right control measures.

2. Managing variations across the farm plot

• Variable Rate Application: This method helps you apply varying rates of inputs in appropriate sections of your farm plot. It would improve your efficiency in application of inputs (fertilizer, water, bio-control agents), and reduce costs. For example, you can apply less water in damp patches of soil.
• Yield monitoring: Mapping the yield patterns along with soil, landscape and environmental patterns would help you determine whether the management of inputs (fertilizer, water, bio-control agents), and techniques adopted are correct or any changes are required.
