PPT-Modelling the optimal phosphate fertiliser and soil managem

James Heppell August 2014 My Research The aim of my research is to model water and P uptake by crop roots and to optimise a sustainable environment for the future given uncertain climate changes and demands from farming restrictions.

Let's look at this anecdote:. “In Uganda, banana trees are growing very well on old abandoned wastewater treatment ponds (as well as on filled pit latrines). The plants take nutrients from the excreta-based sludge in the ponds. People harvest these bananas at night secretly and sell them on the local market. The bananas are tasty and healthy but if consumers knew their origin, they wouldn’t buy them.”. Exploring the importance of minerals to plants. All plants require essential elements that are not supplied by photosynthesis – minerals that are found in soil and absorbed by the plant through its root system..

Keeping soil fertility right is the basis of maximising pasture production. T he key factors are: pH , Nitrogen , Phosphorus , Potassium Conversion rates Kilograms per hectare (kg/ha) are different How to select your cultivar . When it comes to selecting what pasture you want to grow, the first thing you need to know is what sort of paddock you are sowing.. A few things you need to know are the pH level, the fertility status of the paddock, the topography, moisture content, the animals you are going to graze, the time you are going to graze the cultivar, what pests you have, how big is the paddock, how long you are going to graze the pasture and how you are able to sow it..
