Résumé :
The Gardyne Family farm a 710 hectare property at Chatton near Gore in Southland. The property is intensively farmed with 9,375 stock units, sheep and beef being carried at rates of 17.5 su/ha on the cropping property and 12.5 su/ha on the Pyramid Hill grazing property. White clover is the key to animal, crop and herbage production supplying nitrogen for highly productive pastures, building organic matter levels for the cropping rotation, and providing very high quality feed for finishing young stock. Management techniques to maximise clover production are essential and include: (i) use of ade

Résumé :
As the pressure intensifies to reduce nitrogen (N) losses to the environment from pasture-based dairy systems, interest in reducing N-fertiliser inputs and returning to grass–clover mixtures, where more N for pasture growth is supplied by biological N fixation (BNF), have been revived. However, the following question then arises: is BNF fundamentally different from fertiliser N with respect to N losses, especially nitrate-N leaching risk? The present paper addresses this question by reviewing empirical evidence in the context of N-cycling processes and the efficiency of N use for herbage produ

Texte intégral
Résumé :
The physical fertility of krasnozems and euchrozems (Red Ferrosols) in Australia has declined substantially as a result of continuous cropping. Much of this decline is associated with reduced levels of soil organic carbon and soil compaction due to vehicle trac when soils are too wet. We examined the impact of kikuyu (Pennisetum clandestinum) and Rhodes grass (Chloris gayana) pasture leys with various management inputs on the regeneration of physical fertility of continuously cropped krasnozems from 2 locations in the South Burnett region of southern Queensland. Pasture leys significantly impr

Abstract Providing an ideal amino acid profile to horses improves nitrogen (N) utilization and reduces N excretion. This 2-yr study investigated protein concentration and amino acid profile of forages during 84 d of continuous stocking of mixed pastures of rhizoma peanut (RP; Arachis glabrataBenth) and bahiagrass (BG; Paspalum notatumFlüggé) receiving 30 kg N/ha (RP-BG) compared with BG pastures fertilized with 120 kg N/ha (BG-N) or with no nitrogen fertilizer (BG-U). Forage samples were collected on d 0, 14, 28, 42, 56, 70, and 84. All data were reported as percent of crude protein on a dry m

This article presents the extensive agricultural characteristics of fodder plants growing wild in nature, which are the most promising shrub and semi-shrub fodder plants for the creation and development of cultivated pastures in degraded karakul (sheep) pastures. Also, the fact that out of 17.5 million hectares of land allotted for karakul breeding in the desert and semi-desert zones of the Republic, which up to 40 percent are degraded to one degree or another, their average productivity has decreased by 21 percent.

Résumé :
Balancing nutrient inputs and exports is essential to maintaining soil fertility in rainfed crop and pasture farming systems. Soil nutrient balances of land used for crop and pasture production in the south-west of Western Australia were assessed through survey data comprising biophysical measurements and farm management records (2010–15) across 184 fields spanning 14 Mha. Key findings were that nitrogen (N) inputs via fertiliser or biological N2 fixation in 60% of fields, and potassium (K) inputs in 90% of fields, were inadequate to balance exports despite increases in fertiliser usage and ad

The sensitivity of soil organic carbon (Corg) and microbial carbon (Cmic) measurements, and the Cm~,/Co,, ratio, to reflect climatic, vegetation, cropping and management history was investigated using a range of topsoils in New Zealand. The Cmic generally comprised 1-4% of Corg, with the proportion being consistently greater under pastures, than the equivalent soil under native forest, exotic forest or arable cropping. However, absolute values differed markedly between soils and were greatly influenced by texture, mineralogy and the Corg content. The Cmic recovered more rapidly than Corg on re

Résumé :
Clearing natural vegetation to establish arable agriculture (cropland) almost invariably causes a loss of soil organic carbon (SOC). Is it possible to restore soil that continues in arable agriculture to the pre-clearance SOC level through modified management practices? To address this question we reviewed evidence from long-term experiments at Rothamsted Research, UK, Bad Lauchstädt, Germany, Sanborn Field, USA and Brazil and both experiments and surveys of farmers’ fields in Ethiopia, Australia, Zimbabwe, UK and Chile. In most cases SOC content in soil under arable cropping was in the range

The Liangzi Lake Basin (LLB) is an important ecological buffer for Wuhan’s urban agglomeration. It involves the ecological security of the middle reaches of the Yangtze River. Historical land misuse has altered the topography and impacted the ecosystem services value (ESV). Amid urbanization, it is vital to highlight changing land use methods and their effects on ESV valuation, understanding the underlying drivers comprehensively. The research is centered on the LLB as its designated study region, and utilizes remote sensing satellite data spanning from 2000 to 2020. This data is combined with

Abstract Unlike traditional successional theory, Alternate Stable Equilibrium (ASE) theory posits that more than one community state is possible in a single environment, depending on the order that species arrive. ASE theory is often invoked in management situations where initial stressors have been removed, but native-dominated communities are not returning to degraded areas. Fundamental to this theory is the assumption that equilibria are maintained by positive feedbacks between colonizers and their environment.

Abstract One of the most significant differences between the frame stories of Boccaccio’s Decameron and Marguerite de Navarre’s Heptameron is the role of nature and the devisants’ response to it. Boccaccio’s storytellers intentionally flee the destruction and disaster of the Black Death in Florence and look for a pastime that will help them forget their former lives in the city. The men and women of the Heptameron, however, do just the opposite.
