Utilizing Different Crop Rotation Systems for Agricultural and Environmental Sustainability: A Review

open access: yesAgronomy
Monoculture involves growing the same crop on the same land over at least two crop cycles. Continuous monoculture can increase the population density of pests and pathogens over time, thereby reducing agricultural yields and increasing dependence on ...

El olivar andaluz y sus transformaciones recientes

open access: yesEstudios Geográficos, 2011
El olivar andaluz sufrió momentos críticos a lo largo del siglo XX, hasta el punto de ser considerado como un «cultivo problema» durante las décadas que precedieron a la incorporación de España en la actual Unión Europea.

The Subjectivity of Monoculture

open access: yesCoRR
Machine learning models -- including large language models (LLMs) -- are often said to exhibit monoculture, where outputs agree strikingly often. But what does it actually mean for models to agree too much? We argue that this question is inherently subjective, relying on two key decisions. First, the analyst must specify a baseline null model for what

Impact of the Association of Maize with Native Beans on the Morphological Growth, Yield, and Nutritional Composition of Forage Intended for Silage in the Peruvian Amazon

open access: yesAgronomy
Scenarios of climate change, extensive land use, soil degradation, the loss of native forest cover due to monoculture expansion, and pasture scarcity pose new challenges to livestock farming worldwide.

Effect of long-term organic and mineral fertilisation on selected physico-chemical soil properties in rye monoculture and five-year crop rotation

open access: yesSoil Science Annual, 2019
The research was carried out continuously since 1923 in a permanent fertilisation experiment at the Experimental Station of SGGW in Skierniewice. The objective of the research was to determine the effect of long-term fertilisation (Ca, CaNPK, NPK) and ...

Effect of Natural Aging of Biochar on Soil Enzymatic Activity and Physicochemical Properties in Long-Term Field Experiment

open access: yesAgronomy, 2020
The effect of different rates of biochar on selected soil properties and enzymatic activity 48, 60, and 72 months after biochar application to soil was investigated. Soil enzymatic activity (dehydrogenase—ADh; phosphatase—Aph; urease—AU)

Effect of cropping systems on quantitative changes in prevailing weed species

open access: yesAgronomy Science, 2023
A field experiment was established to evaluate quantitative changes in weed species prevailing in a crop rotation and a 30-year cereal monoculture. The subject of the study included cropping systems: a) crop rotation, and b) cereal monoculture.

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

open access: yesFEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Effect of density and mixed culture of largemouth bass (Micropterus salmoides) and pikeperch (Sander lucioperca) on growth, survival and feed conversion rate in intensive culture

open access: yesCzech Journal of Animal Science, 2021
In this study, two experiments were performed with the aim to optimize intensive aquaculture of largemouth bass (Micropterus salmoides). In the first 140-day experiment the effect of the initial fish density was assessed at three levels: low density (LD)
