Environmental modifications for improved grassland production

Abstract

The most important environmental limitations to grassland production are set by the moisture regime, the physiography, soil conditions, temperature, vegetation present, entomological and microbiological factors of the environment. The significant features of these factors are discussed. Modifications which can be applied to overcome these limitations and the resultant degree of grassland intensification (veld, reinforced veld and planted pastures) which can be achieved are suggested and illustrated by means of diagrams. The result of the modifications is determined by the factor which places the greatest limitation on herbage production.

Improved grassland productivity resulting from modification of the environment can be spectacular and is illustrated by specific examples.

Uittreksel

Die belangrikste omgewings beperkinge vir grasveld produksie word bepaal deur vog regime, die fisiografie, grond toestande, temperatuur, huidige plantegroei, entomologiese en microbiologiese faktore van die omgewing. Die betekenisvolle eienskappe van elk van die faktore word bespreek. Aanpassings wat aangebring kan word om hierdie beperkinge te vermy en die daaropvolgende graad van grasveld intensifikasie (veld, versterkte veld en aangeplante weldings) wat behaal kan word word voorgestel en illustreer met diagramme. Die resultaat van die veranderinge word bepaal deur die faktor wat die grootste beperking op produksie plaas.

Verbeterde grasveld produksie wat as gevolg van aanpassings van die omgewings faktore plaasvind kan skouspelagtig wees. Dit word deur middel van spesifieke voorbeelde illustreer.
