If you want to get environmentally friendly crops without making much effort, you must definitely monitor the new products appearing on the world market, which make it possible to facilitate plant care at times. No less close attention should be paid to the inventions of ordinary gardeners: as a rule, cheap in manufacture, not inferior in efficiency to industrial developments, they will help save a lot of time, money and effort. This is the opinion of Nikolai Ivanovich Kurdyumov, the most famous author of books on natural agriculture in our country.
