Improving Acacias in Africa
ISBN: 9783659636967 / Angielski / Miękka / 2014 / 116 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Leguminous tree species such as Acacia could be good candidates to grow in soils very deficient in nitrogen because of their associated rhizobial symbioses constitute a source of N input to the ecosystem. This nitrogen is returned to the soil by the natural loss of leaves which improves the soil fertility and its physical properties through maintenance of soil organic matter, or soil aggregation. In addition, they provide high- quality animal fodder, timber, fuel wood, charcoal, gums and other products. In addition, Acacias are keystone species as they improve soil conditions under their...

Studies on Seed Germination of Some African Acacias
ISBN: 9783659627323 / Angielski / Miękka / 2014 / 148 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Acacia is very important multipurpose genus. Although sexual reproduction in Acacia is the only natural cheapest method for propagation, its seed used to be very dormant and not germinate easily even under favorable conditions, hence the problem of their propagation has to be considered in scientific research. Acacias have a great economic importance and can be utilized in several ways. Acacias can provide lumber, fuel wood, tannin; and many other products. They are also important to pastures and agricultural crops as they can fix atmospheric nitrogen in their root nodules. Their leaves,...
