If the plant is healthy, humans and animals are happy.
Rich in vitamins and free of harmful substances would definitely be a good thing. Unfortunately, home-grown fruit and vegetables are not always free of harmful substances. Industrial plants and intensive agriculture in the immediate vicinity or even the uncritical previous owner can have affected the pollutant situation in the soil.
Fruit and vegetables from our own cultivation offer some advantages. Apart from the fact that it is also a lot of fun to work in one’s own garden and watch the plants grow, one’s own vegetables offer the chance of really good quality. The time of harvest can be optimally selected and varieties can be cultivated which are not (no longer) available on the market. While tomatoes from the greenhouse are often harvested too early, you can wait in your own garden until the fruits are ripe and aromatic.
One problem is that environmental toxins and pollutants cannot be seen or tasted in soil or well water. Long-standing property owners know at least what has happened to their garden lately.
But what does it look like when the allotment garden has been leased? Who can guarantee that the previous owners did not resort to pesticide spraying now and then, and that there are no contaminated sites in the soil? In doubt, nobody. The plants absorb nutrients and pollutants from the soil via the irrigation water. If the water is contaminated with residues, they end up on the plate. Residues that are still stored in the soil are dissolved with the water and then absorbed by the plant.
What to do then? In this case a soil and water analysis is a good way to get clarity.
Pesticides from conventional agriculture or from the use of hobby gardeners can hide in soil and well water.
In addition to the pollutants, the question of nutrient supply also arises, because a good yield can only be achieved if the plants are optimally supplied. If you do not want to rely blindly on a universal fertilizer, you can find an optimal solution with the help of a Mineral material analysis and subsequent fertilizer recommendation. To do this, it is essential to specify the planned main crop. Because every plant has different needs and therefore needs its own mineral recommendation.
