Show THE APPLICATION OF GREEN MANURE Iho va'uo of green manuro Is two fold. Green clover, when turned in tho soil, adds nitrogen directly to 'ho land. Later, when tho clnvcr l being decomposed, tho carbohydrn'or which tho decaying plan contnlm serves as a sourco of energy for the oliiss of sold ba:tcrln that aro ahlr to gather freo nitrogen, Indepcnden' ')f a host plant, from tho nlr Into tli' colls In a form that will bo later used by growing plants. Owing to tin oase and quickness in which tiicsi green crops may be decomposed, the stimulation of the independent fruc nitrogen fixing bacteria Is broght about much socner than will dry ma terlul that Is coarso and difficult to decomposo. If during a dry spell the gieeu ma nuro Is ndded in very great quuntl ties, oxcesslvo evaporation may ru suit Kxporlmcnts havo shown that acid produced In tho soli from this kind of manuring Is not great enough to, prevent nitrification. Tho farmer must uso Judgment In selecting tho most economical crop for thin purposo In his particular sec tlon. Tho one giving a luxuriant .growth of leavos and costing but lit tlo to grow Is desirable. A nou le gumlnous innt Is as valuablo In stlm ulatlng tho freo nitrogen fixing or ganlsms, pound for pound, as the plants of tho leguminous fnmlly. The fact that a plan Is not from tho lo-gumo lo-gumo family docs not keep It trim being or valuo as manure. This form of manuring bids fair lo receive a great deal moro of attention in the near future. Idaho Experiment Station. |
