Seed Rain Of A Native Pasture Under A Range Of Grazing And Fertiliser Regimes, Zhongnan Nie, Reto Zollinger Dec 2019

Seed Rain Of A Native Pasture Under A Range Of Grazing And Fertiliser Regimes, Zhongnan Nie, Reto Zollinger

IGC Proceedings (1997-2023)

In recent years, deferred grazing (no defoliation of pastures for a period generally from spring to late summer or autumn) has been widely adopted to rejuvenate degraded native pastures in marginal land classes such as steep hill country in western Victoria, Australia. One of the important features of deferred grazing is the increase of seed production over summer and autumn, which could potentially lead to natural regeneration and improved groundcover by pasture plants (Nie et al. 1999). While increasing seed numbers in the soil seed bank following deferred grazing were reported (Nie and Mitchell 2006), there has been little …


Some Aspects Of Assessment Of Soil Fertility, R. Qo’Ziev, N. Abduraxmonov, N. Хalilova Jun 2019

Some Aspects Of Assessment Of Soil Fertility, R. Qo’Ziev, N. Abduraxmonov, N. Хalilova

Scientific journal of the Fergana State University

In the article, it is shown that soil is a complex object to evaluate its fruitfullness, as well as analyzed different methods in this sphere. It emphasises the integrity of the usage of models of soil on evaluating of its fertility, the soil has its characteristics and peculatities and its formation of fruitfulness are conditioned by definite conditions.

Residual Soil Phosphorus In Tropical Oxisols: An Opportunity To Enhance Fertilizer Use Efficiency?, Lauren Bomeisl Jan 2019

Residual Soil Phosphorus In Tropical Oxisols: An Opportunity To Enhance Fertilizer Use Efficiency?, Lauren Bomeisl

Graduate College Dissertations and Theses

Phosphorus (P) is essential to life on Earth and often the limiting nutrient in agricultural systems. P fertilizer is thus an essential resource to maintain food security. In the last half century, agricultural intensification has led to an increase in P fertilizer consumption from 4.6 to 17.5 Tg of P/year to meet rising global food demand. Mineral P (i.e., phosphate rock) is a non-renewable resource in the context of the Anthropocene, and its price is vulnerable to global market fluctuations. Increased efficiency of P use on farms is considered the most effective strategy to conserve P. The soybean industry demands …
