Role of phosphorus as a key component for managing grasslands N-yield and phytodiversity in organic farming
Project
Project code: 2812OE008
Contract period: 01.09.2013
- 31.08.2016
Budget: 119,224 Euro
Purpose of research: Applied research
This project targets on assessing the effect of phosphorus soil status on the botanical composition of organic farmed grassland with special regard to perennial legumes, their functionality and grasslands phytodiversity. For this purpose field investigations are planned at three soil types (salt grasslands; low peat grasslands; moraine grasslands) accommodating quite a number of characteristically species. These field surveys focus on occurrence of permanent legumes, especially on Trifolium repens, at different spatial scales in relation to respective soil and plant-P contents. Any P-thresholds should be identified by statistical analyses based on the collected data considering both legume performance and biodiversity. Furthermore, field experiments conduce to open new opportunities for P-fertilising as a tool in organic forage production to regulate legume growth and N-yields. The results will be made available to the advisory services and farmers and to the nature conservation administrations too.
