Robinier mangium plants were cultivated in a container culture medium of mud supplied with Total and Without Nutrient Solutions to study the nutrient position of the plant life and their influence on growth under different nutritional treatments.

The nutritional status from the plants were determined by studying the 6th leaf from the bud-tip of secondary divisions in the lower canopy which has been found to show relatively stable macro-nutrient amounts from one herb part to a new within a particular plant.

The effect obtained from this kind of experiment shows that the the best 6th tea leaf nutrient amounts for the various plant nutrients are: L: 0. 20-0. 23 %; Mg: zero. 17-0. twenty-two %; Mn: 140-190 ppm.

N and K levels fluctuated at two distinct ranges in different times, but had been always above 2 . 60 % N and 1 . 00 % K in plant life where these types of nutrients had been provided.

Ca, H, Fe and B answers are such that simply no inferences could possibly be made with an affordable degree of certainty. However , California levels primarily fluctuated between 0. 35-0. 55 %, S between 0. 20-0. 35 %, and Fe between 40-80 ppm.

The Less Boron treatment resulted in the leader shoots with the plant declining off and caused the deformation of new leaf buds to seriously have an effect on growth. This could occur in levels below 10 ppm but will certainly occur for levels under 5 ppm. In treatments where Boron was provided, their levels generally fluctuated between 20-70 ppm.

A linear growth charge pattern, while shown by simply Relative Amount calculation via height and girth measurements, were seen for those plants treated with Complete Chemical Solution (the Control) when optimum nutrient status have been reached. Ahead of reaching this kind of nutritionally optimum status, the Relative Quantity showed a great exponential growth pattern. The growth pattern of the various Less Nutrient Remedy treatments was similar to the control, although in some instances, a slight deviation was noticed for a short time, indicating an alteration in the development rate.



Acacia mangium is a legume tree types native for the marshy areas of tropical Down under. It is naturally hardy and fast developing (even upon poor soils), and is consequently being cultivated in logged over areas to combat deforestation and erosion moreover to providing a future method to obtain timber and pulp.

It is important to identify nutrient deficiencies of this species as it is staying planted upon such a big scale necessitating high levels of capital inputs. Thus chemical deficiencies impacting on its development (and hence its benefits) need to be identified, quantified and subsequently remedied through manuring as financially as possible.

For the purpose of manuring the species economically, the nutrient position of the flower needs to be discovered by both visual and foliar analysis, and its nutritious status relevant to the growth and yield from the species.

This paper describes and discusses the results extracted from a container culture test set up for Agricultural Exploration and Exhortatory Bureau to determine optimum foliar nutrient amounts for maximized growth of A. mangium. Nutritional deficiency symptoms observed although carrying out the experiment were also recorded.

It can be envisaged that fertilization of the. mangium during a call will be targeted to achieve this kind of nutrient levels if the economics of doing thus prove practical.


Institution of Pot Culture

Acacia mangium was grown in 40 twenty-five liters clay containers with glazed inner and outer floors and stuffed with fine sand. A sand particle size of 0. 6 -- 1 . six mm was used to provide cost-free drainage along with suitable normal water holding capability (12. 2%). The containers had a essentiel outlet as a installment payments on your..
