Sažetak
Crowdsourcing as outsourcing data collection by a network of farmers (the contributors) that are not doing so for their normal professional activities is used more and more intensively in the digitalization of agriculture. In agriculture it can be called “farmsourcing” if involves professional stakeholders in the agriculture sector working on a voluntary basis to exchange information. The aforementioned crowdsource format was used for the 4-year collection of 4 groups of data on arable crops growing (1. crop, pre-crop and yields ; 2. organic fertilization ; 3. harvest residues ; 4. mineral fertilization). Data were collected from 13, 239 requests for soil analysis. The most complete data were collected for the planned crop (99.6%) and pre-crop (97.57%), but at the same time, 30.87% of the producers did not provide data on the planned yield, and 36.82% on the realized yield of the pre-crop. Data on harvest residues was provided by 62.1% of users, and slightly more on applied fertilization (64.85%). In total, producers provided 68.65% of the requested data on average. The analyzed data showed monoculture on 13.6% of all the analyzed requests, including alfalfa, clover, pastures, meadows and perennial grass mixtures (3.3%). The most common crop in monoculture is corn (8.26% of all requests), but there are significant areas with successive sowing of small grains (2.22%). Also, soybeans (0.48%), wheat (0.42%) and ryegrass (0.32%) appear in monoculture more than other crops. According to the collected data, harvest residues were returned to the soil in 71.22% of cases, and removed from 28.76% of the areas. The largest share of the removed residues were small grains (71.6 %), but a significant share was corn for grain (7.2 %), sunflower (1.4 %) and rapeseed (2.12 %). Also, 75.4% of producers applied fertilization according to the needs (in the range of 70%-120% of recommended fertilization), 18.3% in the range of 40-70% of recommendations, and 3.7% did not use fertilizers. By combining the results of laboratory analyzes and collected data, it is possible to find connections between crop cultivation, agrotechnical measures (organic fertilization, crop residues, fertilization level) and soil fertility with planned and realized yields, which shows the significant potential of crowdsourcing.
