Some considerations on factors affecting rangelands

in STEMGeeks9 months ago (edited)
Dear readers, a system consists of several components that are related to each other for a common purpose, in the case of livestock production for example involves human talent, machinery, soil, pastures, fodder, animals and perimeter fences. Biotic and abiotic factors such as temperature, rainfall, solar radiation and relative humidity are involved in agroecosystems, which significantly influence rangeland yield and quality.

In this sense, the pastures have their own characteristics that provide specific adaptation for their growth and quality, however, they experience changes in performance when changes occur in climatic conditions such as temperature, solar radiation, relative humidity and precipitation being these determining factors in livestock activity in tropical areas.

According to the mentioned, it should be noted that, temperature is one of the most relevant factors in the growth and development of pastures thus determining the quality of the pasture as , structures cell walls thicken conviritiendose in poorly digestible for cattle also, Genetic factors such as the species and chemical composition of plants determine the efficiency of foliage from a nutritional point of view. Likewise, non-structural carbohydrates such as monosaccharides, disaccharides and oligosaccharides present in the upper part of the plant increase digestibility and palatability according to the phenological stage found in said pasture.

The growth potential of tropical grasslands tends to be more accelerated by the metabolic pathway used to carry out photosynthesis, Known as C4 plants their efficiency lies in that they do not photobreathe and always have carbon dioxide available for the photosynthetic process without risk of taking O2 oxygen. In this sense, it can be said that the productivity of grasslands depends on the conversion efficiency they make of atmospheric CO2, nutrients, soil moisture and solar energy, These factors are highly influential in the production and quality of pastures according to the type of plant that exists in the livestock ecosystem.

Due to the above, it can be evidenced in some tropical livestock ecosystems of the south of the lake of maracaibero problems of low productivity in cattle herds. Among the main causes of this are the low quality of the grasslands and the high level of degradation that these have by carrying out erroneous practices within the integral management of the agro-ecosystem. In turn, man is considered one of the main factors influencing the growth of pastures when they do not know the phenological stages and the cultural or agronomic practices that must be followed for the efficient yield of biomass. In addition, the animal load, rest days and occupation must be taken into account according to the type of grass that is established.

Finally, dear readers, it is evident that the changing climate that is currently experienced by the natural phenomena that exist leads to an integrated management of the livestock system being increasingly demanding efficiency among man-soil-plant-animal, training is necessary for the agricultural producer who often does not know the importance and relevance of producing pastures of high nutritional quality to then obtain a production of meat or milk and/or dual purpose where all resources are used.

From agrotecnia we reiterate our gratitude to our followers and all the communities that value our agricultural content, this commits us to continue sharing quality information with the whole hive.


Climate change is definitely a game changer here. We already observe a lot of local changes by just the conditions usual for one place moving to another place. I like to say that usually, the future looks bright. But here, it does not...

Thanks for sharing this information with us!


Greetings dear @lemouth, thank you for leaving your valuable opinion about it, I can say that previously the teaching methods of agriculture were based on the use of technological packages depending on the type of crop, At present, it is no secret that excessive use of these methods has deteriorated the biodiversity of agricultural systems in addition to significantly influencing climate change.

At present the productive model is based on knowing the natural processes, it could be said that it is the traditional agriculture of our ancestors but with the scientific touch that influence certain phenomena in food production, In other words, we adapt to what is now known as sustainable development.

So long, have a great week.

Thanks for coming back to me. I however wonder whether our adaptation is fast enough. I am not very sure about it, but this cannot be answered. Only the future will tell...


Hello friend, certainly the future is uncertain and only time will tell how far we will advance in the agricultural field, In order to make progress, extension programs must be carried out to convince the producer that these new technologies are appropriate according to the context in which we find ourselves. The producers have a kind of blockade for lack of information and they cling to other methods, it is something cultural so to speak. When we started with the electric fence to delimit the forage areas, many producers in my country refused to use them, but then, they were educated about it and settled in several farms with some trials and began to massify said method.

Education plays a determining factor and agrarian universities have the responsibility through the extension of socializing the research carried out by their researchers and not cloistered in libraries.

So long, greetings and successes !

I fully agree with the points you raised. Education plays the determining role and with time, mentalities will change. The good thing is that we have examples of the past in which this happened and worked for the best. Then maybe we will get there faster.
