Crop yield estimation

Crop management is a critical part of agricultural productivity, and efficiently maximising crop yields for a higher crop demand has become a pressing global challenge. However, many current agricultural practices seek to meet this yield demand by applying an overabundance of agrochemicals, which leads to soil and ground water contamination. To enhance crop yield while overcoming environmental challenges, the concept of precision agriculture (PA) was introduced putting forward the idea of sustainable site-specific management by applying the right management practices at the right place and right time using variable rate technologies by taking into account the spatial variability of agronomic conditions of crops. The PA approach is in contrast to traditional farming, where farms under conventional management receive uniform application of agronomic inputs. Uniform crop management based on the field average would apply too much fertilizer on areas in a field where crop yield potential was low and would apply too little fertilizer where crop yield potential was high. In practice, farmers apply fertilizer at rates in excess of requirements for areas in the field with the highest yield potential. Today, precision agriculture embraces all agricultural inputs and management options based on site-specific information. With precision agriculture, fields can be divided into management zones that each receive customised management inputs based on varying soil properties, plant condition and management history. This concept deals with efficiently maximising crop yields without unnecessarily depriving resources or without degrading soil with intensive agricultural practices. Sustainable agriculture through precision farming has been recognised as a need of the day, effectively responding to the challenges in hand. At SAPD Engineering we provide range of site specific agriculture services to enhance the productivity and profitability agriculture through state of the art spatial science technologies. Our remote sensing solutions for agriculture capture your farm’s critical data, converting it into actionable information to support real-time decisions. Collected imagery is converted in to valuable information validated with field sampled data and remote sensing driven information is uploaded to a geographic information systems (GIS) program to developed zonation maps which displays the spatial variation of soil and crop status. Crop and soil status zonation maps are used to suggest agronomic practices and finally maps showing different zones of agronomic application are provided which can be used variable rate application manually or by uploading electronic maps to variable rate controllers to conduct variable rate spreading.
