“…Membe biophysical changes reduce productivity as well as signal anthropogenic thresholds (Ureta & Otaegui, 2021). It is crucial for each successive government to form a consistent agrifriendly policy in order to satisfy the credit requirements of the rural agriculturalists for the growth, stability, and survival of the agricultural sector.…”

The aim of this study is to determine the role of Farm Advisory Services in order to offset the problems of the yield productivity gaps in the study area. The farmers’ perceptions of the Model Farm Services Center (MFSC) were statistically examined via a comparison of the differences within two subgroups. A sample size of 120 was selected in order to enable equal representation from both the member farmers and the independent farmers of the MFSC. An independent sample t-test along with a dummy variable was used to identify differences in their farming practices and obtained yield respectively. It was found that 80% of the respondents entirely relied on farming, whereas 20% only partially relied on farming. Similarly, 70% of the farmers were living in a joint familial system, while 30% of them were individual households. Furthers some of the farmers 28% used canals while only 13% relied on tube-wells from the member respondents, whereas 30% of the independent farmers relied on canals and 10% used tube wells. The independent farmers were more productive with wheat, rice, and sugarcane crops, but a lower yield with the maize crop was identified compared to the member farmers. The study concludes that there are inefficiencies and gaps in the service delivery value chain of the MFSCs and recommends actions, such as by providing basic farm inputs, modern equipment, interest free credit as well as technical guidance. The study contributes by using the farmers’ perceptions as a stepping stone for the policy input in regards to the agriculture laden productivity.

“…The International Commission for Anthropogenic Soils (ICOMANTH) was established in 1995 in the United States to deepen the study of anthropogenic soils. International scholars have studied the properties, classifications, management, functions, and cartographies of anthropogenic soils [12][13][14][15][16][17][18][19][20][21].Some scholars have explored the investigation and taxonomy schemes of such soils, exploring the rationality of their national taxonomy schemes based on the results of engineering soil classifications, and they have provided suggestions for improvement [22][23][24][25][26][27][28][29][30][31][32]. Capra et al summarized numerous suggestions for classifying human-altered and human-transported soil studies [33,34].…”

As global industrialization and its associated anthropogenic activities rapidly increase, so too does the areal extent of human-altered soils. The soil classification framework must incorporate the classification schemes of these disturbed soils in order to remediate land. Soil Taxonomy (ST) and the World Reference Base for Soil Resources (WRB) are the most widely used soil classification systems in the world. In this study, 15 typical anthropogenic soil profiles with engineering and technical characteristics from China were selected for a classification study. The aim of this study was to clarify the classifications of these soil profiles in the ST, WRB, Chinese Soil Taxonomy (CST), and Geogenetic Soil Classification of China (GSCC), and make references accordingly. The results showed that the WRB can classify these soils as Technosols in the first level. ST can classify most of these soils as subgroups within the different great groups under Entisols, as well as the Human-Altered and Human-Transported Material classes within the soil family differentiae. For Chinese soil classification schemes, there is a large loophole in the CST regarding the classification of anthropogenic soils. Many anthropogenic soils cannot reflect these soils’ artificial and technical naming characteristics. For the CST, revised proposals based on the WRB and ST were proposed. Based on the artificial disturbance of soil layers, a manufactured layer was added to the diagnostic basis. The Artificalic Anthrosols suborder was added, and it can be divided into the Transporti-Artificalic Anthrosols and Alteri-Artificalic Anthrosols groups. The subgroups were defined by their levels of contamination, imperviousness, and artifact content. The “T” layer symbol was added to soil profile descriptions to reflect a specific layer about technology, such as A, E, B, and C, to reflect the main genetic horizons. This revised classification system is proposed for inclusion in the revised CST to account for the very large and expanding extent of disturbed soils in China and to remain current with other global soil taxonomy systems.
