Over grown wih weeds

I grow up these grass,because I want to do circulate way.These grass will return to the earth and give nutrition too.What  a great planet the earth is.
However Japanese old generation people belive the farm needs agricultural chemicals and even does't need grass too.They belive Japan agricultural cooperative association(we call JA).What do you think?We don't need any chemicals on our land.They kill our land,but old people especially traditional farmer think the farm needs chemicals.
They don't know what's JA is.JA sell harmful chemicals and kill the land so land needs nutrition,then sell many chemical nutrition so they made so huge profit.Therefore,my teacher of this farm she is 85years old.She wants to sprinkled chemicals,but I don't.And she does't understand this theory,or maybe she doesn't ask this sort of things.Now I decide find the another field and do my sytle.I don't know when,but Absolutelly I will.
