Organic & Natural Fertilizers

Organic fertilizers are defined as products derived from either animal and vegetable forms which have some fertilizer properties and normally, but not always contain N.P.K. fertilizer. Examples are bone meal, fish meal and animal manures.

Natural Products are mineral type products mined from the earth. They are not chemically processed but are normally crushed to make them more active. They usually contain trace elements and are often effective as soil conditioners. Typical are limestones, gypsum, rock potash, kieserite, kainit etc. which are often mistakenly described as organic.
