Abstract The fast and broad adoption of mechanization chemical inputs in Mediterranean terraced agriculture, combined with warming climate trends, has led to the progressive degradation environmental social conditions. These factors have concurred increasing abandonment smallholder agriculture. We aimed detect quantify progression cultivated abandoned fields Ricote Valley between 2016 2019 whil...

History of wheat cultivation is as long history civilization. Adaptation nature, animal domestication and plant cultivation, enabled transition from nomadism to sedentism 12,000 years ago, portraying the rise Homo sapiens today. First civilization, Mesopotamia aroused around 4000 B.C.E, in riverbanks Tiger Euphrates, where carbon-14 dating revealed that tetraploid wild emmer (Triticum turgidum ...

In response to a shift toward specialization and mechanization during the 20th century, there has been momentum on the part of a vocal contingent of consumers, producers, researchers, and policy makers who call for a transition toward a new model of agriculture. This model employs fewer synthetic inputs, incorporates practices which enhance biodiversity and environmental services at local, regi...

The main purpose of this paper is to give a simple and non-combinatorial proof of the toric Mori theory. Here, the toric Mori theory means the (log) Minimal Model Program (MMP, for short) for toric varieties. We minimize the arguments on fans and their decompositions. We recommend this paper to the following people: (A) those who are uncomfortable with manipulating fans and their decompositions...

The article presents the mechanization of the process for obtaining powdered cellulose using the technology of steam explosion treatment of lignocellulosic material. The presented unit combines the methods of steam explosion treatment and acid hydrolysis of cellulose-containing raw materials.

Global mechanization, urbanization, and various natural processes have led to the increased release of toxic compounds into the biosphere. These hazardous toxic pollutants include a variety of organic and inorganic compounds, which pose a serious threat to the ecosystem. The contamination of soil and water are the major environmental concerns in the present scenario. This leads to a greater nee...

Based on panel data for the inputs and outputs of three major staple grains (rice, wheat corn) in China from 2000 to 2020, we calculated cost efficiency using stochastic frontier function model examined effects changes explore sources increases grain production. On this basis, impact input factor structures technical food was further analyzed under conditions price increases. We found that labo...

In order to improve the prediction accuracy of agricultural machinery total power then to provide the basis for the agricultural mechanization development goals, the paper used gray GM(2,1) model in the prediction. Through the introduction of parameter λ to correct the background value and parameter ρ for multiple transformation on the initial data, the model was expanded to (2,1, , ) GM λ ρ mo...

Mechanization and simplification are inevitable trends in agriculture production to decrease input demands and simultaneously improve resource use efficiency. Dry direct-seeded rice is a resource-saving cropping system and has been considered as a replacement for traditional transplanted rice. However, the poor establishment of dry direct-seeded early rice, primarily induced by chilling stress,...

(2017): Evaluation of genetic diversity and population structure of five Chinese indigenous donkey breeds using microsatellite markers. Czech J. Anim. Sci., 62, 219–225. China had the largest population of raising donkeys in the world, however the number of Chinese indigenous donkey decreased dramatically ...
