When applying Urea as second application, does it require digging a hole and bury or can be placed beside the plant. Urea is soluble while NPK is granular.
The movie is nice and shows a goodwill, however, there should be some inidcations about what is "just enough" fertilizer per plant or hectare. Also, should be few words about the linkage of water and fertilizers are essential, especially these days when rain become erratic.
I recommand the Zai technique which consist of digging small holes in the ground where seeds will be planted. Fertilizer will be precisely put in these holes instead of spreading all around the field. These technique save a lot of resources first of these are fertilizer
Is it certain that the mineral fertilisers do not wash away? I am learning that they do wash away and Ammonium NH4 washes almost as easily as Nitrate NH3. Any clarification to my learning would be appreciated. Thank you
