The effect of environmental factors on the growth of a natural pasture

Agricultural Meteorology, 1975
Abstract In order to study the dependence of growth curves of a natural pasture on environmental factors, logistic equations in which the growth rate R is a function of soil moisture or temperature are used. The parameters that appear are optimized by a nonlinear least-squares technique. Soil moisture is an important variable.

Structure Differences of the Natural Insect Enemy Complex between Jujube Orchards Intercropped with Pasture and No Pasture

2009 3rd International Conference on Bioinformatics and Biomedical Engineering, 2009
The communities and diversity of the beneficial insects on jujube trees were studied in jujube sites intercropped with pasture in Taigu, Shanxi province of China. The results showed that 8 orders, 25 families, 64 species and 5112.33plusmn30.65 individuals of insect natural enemies were found in the jujube sites intercropped with pasture site, while the

Molecular Diversity of the Rumen Microbiome of Norwegian Reindeer on Natural Summer Pasture

Microbial Ecology, 2008
The molecular diversity of the rumen microbiome was investigated in five semi-domesticated adult female Norwegian reindeer (Rangifer tarandus tarandus) grazing on natural summer pastures on the coast of northern Norway (71.00 degrees N, 25.30 degrees E). Mean population densities (numbers per gram wet weight) of methanogenic archaea, rumen bacteria and

EFFECTS OF IRRIGATION AND NITROGEN ON A NATURAL PASTURE SWARD

Canadian Journal of Plant Science, 1978
Irrigation and nitrogen (N) requirements of a natural pasture sward were studied on a Charlottetown sandy loam soil over a 5-yr period. The soil moisture content at the 0-to 15- and 15- to 30-cm depths was determined at from 7- to 10-day intervals, while irrometer soil moisture readings at 15-, 30-, and 45-cm depths were recorded more frequently ...

Influence of pasture-protective forest belts of black saxaul on natural pasture productivity in the desert

Кормопроизводство, 2017
В работе освещены результаты разработки способов создания пастбищезащитных чёрносаксауловых полос и их положительное влияние на пастбищную растительность, произрастающую в условиях пустынь и полупустынь среднеазиатского региона. На участках, пригодных для произрастания саксаула чёрного, создавались пастбищезащитные полосы шириной 15–25 м, посев ...

Autecology of some natural pasture species at Trangie, N.S.W.

Australian Journal of Botany, 1954
Features of the autecology of four native perennial grasses (Stipa, Chloris, and Digitaria spp.) and an important group of winter annual species are reported from a 5-yr study of a naturaI pasture at Trangie, N.S.W. The investigation was mainly concerned with the response of the species to changes in seasonal climatic conditions. The study period (1948–

A review of experiments comparing systems of grazing management on natural pastures

Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1978
Experiments comparing different systems of grazing management on natural pastures in various parts of the world are reviewed. In experiments in which various rotational systems were tested against continuous grazing, fewer than half revealed pasture improvement relative to continuous grazing.

Management of natural pasture resources

2002
The Adriatic area of Croatia is a typical example of Mediterranean ecosystems, as shown by the economy, culture and civilization. This area covers more than one third of the entire territory of Croatia (2.020.000 ha or 35.7%). Agricultural areas within the Adriatic littoral represent more than one third (34.3%) of the total agricultural area of Croatia.

Domesticating Shrubby Native Legumes for Pastures and Natural Grasslands

2018
As ruminant species diversify in natural and managed ecosystems in an effort to increase production, so does the need for greater plant diversity. Legume shrub propagation is rarely targeted for this purpose. As an example, the wide range of native perennial, shrub (0.5–3 m) legumes in Texas indicates untapped potential for multiple uses such as forage,
