Organic Manures 



fertilising matter contained in loo parts in the 

 following green manures : — 



It is advisable to use green manures on a large 

 scale particularly where farmyard manure is scarce, 

 and also where the regular cultivation of catch- 

 crops is not possible. It should be sown along with 

 the wheat. 



If possible it should be ploughed in when the 

 greater number of the plants are in flower, this 

 being the time when they contain the maximum 

 amount of fertilising matter and also the greatest 

 bulk of humus, and when the latter is in the form 

 most easily broken up and assimilated. The 

 manures should be buried some time before the 

 sowing season and should be in process of decom- 

 position before the autumn wheats are sown, because 

 these do not like a soil that is not well settled. 

 Green manures are usually followed by a wheat 

 crop. Pastures converted into arable furnish a 

 cheap green manure and give good crops providing 

 that they are given assimilable phosphates and a 

 little potash. 



Farmyard Manure. 



For hundreds of years farmyard manure was the 

 only fertiliser employed on the land. It was upon 

 this manure that the restitution depended. We have 

 seen what losses of fertilising matter it undergoes,
