From the point of view of the agricultural company producing food, depending on the amount of land owned by the owner, the ideal is to diversify the production unit, when I talk about diversification I mean to make a spatial arrangement where in the whole area a part is destined to the cultivation of pastures for the management of animals and the production of milk and meat and another part for fruit crops, vegetables and others, depending on the climate and soil type. It can also be diversified only with crops for human consumption. Diversification allows maintaining a nutritional balance in the soil, especially when there are crops from different families because each one has different nutritional needs, therefore there will not be an excessive extraction of a single element. On the other hand, a monoculture depletes certain nutrients from the soil, which must be replenished quickly with synthetic fertilizers, since organic fertilizers generate medium and long term responses.
On the other hand, whoever wishes to go into the raw material processing industry or animal feed production, will logically first have to carry out a market study to know the demand for such product, for example, in the area where I live there are several dairy industries and industrial slaughterhouses, since livestock farming is predominant in the area.
As for getting reliable external resources, I mean that any product that we acquire in the production unit must be guaranteed and provide the nutritional elements or the quality required. For example, as a specialist in the forage area, I have noticed in my sector, that many producers make silage (fodder conservation by fermentation) but do not comply with the necessary standards for implementation, therefore, the harvested fodder will not have the quality that is needed on the farm for animal nutrition in times of drought. Then the farm can not risk capital in products that do not provide the necessary quality, likewise occurs with some fertilizers that are marketed without knowing their nutritional and microbiological values as discussed in the article.
Thanks for your visit, I will take my answer as part of the content of a future article and I will expand it a little more, thanks to your comments I can visualize interesting topics that I can address in my blog.
See you later, have a great week.
