Fertilizer Tools: fall 2020 Tri State Fert recommendations in a spreadsheet.Silo Capacity: capacity and inventory in tower and bunker silos.Purdue Crop Planner: by-field planning with tallies for cropping inputs across the farm enables comparison of different strategies.Generic Records Generator: a pp-like spreadsheet for logging and tallying events, activities, etc.Animal Vaccine and Meds Records: app-like spreadsheet for livestock treatments - includes recommended dosage based on estimated weight.Fertilizer Records & Inventory: app-like spreadsheet for fertilizer records that also updates inventories.Planting Records and Seed Inventory: app-like spreadsheet for planting records that also updates seed inventories.Field Metadata Tool: app-like spreadsheet for digital field records.Transfer and Inventory Googlesheet: app-like spreadsheet for improving transfer and inventory records.Manure Records: app-like spreadsheet for generating manure spreading records.Manure Balance Tool: for a hobby or small farm, compute the nutrient balance from livestock & crop.Tractor Ballasting: computes weight distribution for optimizing tractor performance.Cycle Analysis: evaluation of cycle analysis of machinery interactions such as during harvest (harvest, transport, unload).Hay Storage Evaluator: compare in-barn, covered with tarp, or outside uncovered hay storage options (dated style).Benchmarking Tractor Costs: tally costs of alternative tractor sizes & designs to enable benchmarking for lease, buy, rent decisions.Phosphorus Cost Comparison: estimate machine capacity (ac/h) needed to cover a target land area in given time window, then also compute capacity from implement descriptors.Machine Capacity: estimate machine capacity (ac/h) needed to cover a target land area in given time window, then also compute capacity from implement descriptors.While the list is below, we have also put together a spreadsheet toolbox (well just a spreadsheet listing spreadsheets if you can imagine that) that you can access through Google and search by category and topic. This list will grow over time so be sure to check back often. We have compiled a list of more than 30 spreadsheets created at Purdue University on topics of field crops, fertilizer recommendations, economics, data management, animal agriculture, and more. We presume farms and agribusinesses use them extensively whether the user does the programming or just uses pre-set configurations of tools. Spreadsheets come an many sizes and shapes and are a computational tool used for an unbelievable number of quantitative decisions.
