FOR SOME YEARS NOW, J. P. Beggs, Farm Advisory Officer at Blenheim, has been concerned with problems of establishing legumes in the hill country about Blenheim. The natural cover on this country consists of an almost pure sward made up of five species of Notodanthonia. Because of the steep nature of the country, oversowing is the only practical method of pasture improvement, and this fails beca...

Land-use change accounted for 18% of global greenhouse gas emissions in 2000, making it the second largest source of emissions, after the power sector. These emissions arise from a change in the management of land by humans, such as conversion of forests to pasture land. The following sections will explain the role of the land, that is plants and soils, in the natural carbon cycle, and how chan...

The development of the non-woolled Dorper sheep breed is briefly reviewed. Despite the large number of Dorpers in South Africa, precious little research results have been published on its nutrition under harsh, arid grazing conditions, especially since this has been an objective for creating and developing the breed. Results from the limited number of trials with free ranging Dorpers on natural...

Pasture-based cattle farming has dramatically modified the rural landscapes on a continental scale and has been recognized as a process with huge environmental and social impacts. In Latin America and the Caribbean region, there are currently more than 602 million hectares occupied by permanent pastures, which accounts for more than 33% of the said region (Chará & Murgueitio 2005). Cattle produ...

Control of nematode parasites with reduced reliance on the use of anthelmintics was studied in 16 ewes with suckling twin lambs on contaminated pasture in Denmark. Ewes and lambs were treated with albendazole at turn-out 3 May. Ewes were removed from the groups on 26 July, and lambs were slaughtered on 11 October. The animals were allocated to 4 groups of 8 lambs and their 4 ewes. Group TS was ...

With high dry matter yields of high quality forage, high soluble carbohydrate levels and a suitability for harvest by cutting and removing, the forage legume sulla (Hedysarum coronarium) has the potential to be an important silage crop in New Zealand. In three experiments the ensiling potential of sulla was compared with conventional pasture using a mini-silo system which allows for rapid evalu...

Land use changes in the Everglades Agricultural Area (EAA) of south Florida may alter microbial activity and organic matter decomposition and ultimately influence the fate of P in soil. The objectives of this study were to determine effects of long-term cultivation and fertilization on microbial activity and P dynamics for contrasting land uses in the EAA. Soils (0-15 cm) under pasture for 100 ...

. The objective was to study the habitat complexity of mite populations on Caryocar brasiliense trees under natural and cultivated field conditions. performed in municipality Montes Claros, state Minas Gerais, Brazil, over 3 years. Three types areas were studied: 1) Cerrado, 2) pasture, 3) a university Campus. Several chlorotic spots detected leaves with larger Tetranychus sp. Eutetranychus (Te...

BACKGROUND Gene expression analyses are used to investigate signaling pathways involved in diseases. In asthma, they have been primarily derived from the analysis of bronchial biopsies harvested from mild to moderate asthmatic subjects and controls. Due to ethical considerations, there is currently limited information on the transcriptome profile of the peripheral lung tissues in asthma. OBJE...
