Aims: Soil structural deterioration and degradation is a major concern in the present-day agriculture scenario. Poor soil health directly affects the health of the plant and its productivity; indirectly the health of human beings as well as animals. So, scientific knowledge of soil management on the part of the farmer-producers is necessary. So, the main aim of the study is to identify the knowledge level on soil health management among the soil health card holders. Study Design:  Ex-post facto research. Place and Duration of Study: The study was carried out in the Namakkal district of Tamilnadu during the months of July-August 2021. All the selected respondents were the holders of soil health card as it contains physical and chemical characteristics of soil, they have a working knowledge of research problem and were able to provide responses. Methodology: Data were collected by using a pre-tested and structured questionnaire through a face-to-face interview method. The sample size is 120 selected from four blocks of Namakkal district. The statistical analysis applied were frequency distribution, percentage analysis, mean, and standard deviation. Results: The study shows that more than half of the soil health card holders (55.83 percent) had an overall high level of knowledge about soil health management practices. Conclusion: The soil health card scheme was brought to bring improvement of soil health in the long run by farmers all over the country. Thus, the knowledge of soil health management practices including modern technology can be disseminated to a greater extent for the benefit of the farmers including non-holders of soil health cards through formal and informal meetings and training.

This trial study examines barriers to the diffusion and adoption of an agricultural concept surrounding soil health as an improved management tool which has most recently been introduced into production agriculture. For this study, a small sample set of perceived early adopters of soil health management practices were interviewed for their perspective on the subject of diffusion of innovation in soil health. Rogers' (1995) diffusion of innovation serves as the theoretical underpinning for this study. Where "an idea, practice or object that is perceived as new by an individual or other unit of adoption". H. F. Lionberger from the Department of Rural Sociology at University of Missouri was one of the contributing authors and had previous publications (Lionberger, 1957, 1960; Lionberger and Gwin, 1991). While diffusion of innovation has provided an overview of how information is diffused and adopted for Extension professionals, academia, and students, its use in discerning the adoption of soil health management practices has not been examined previously. There were both differences and similarities in what experiences, attitudes, and beliefs shaped the early adoption of Soil Health practices and how each interviewee perceived the most limiting factor 38 of adoption from other producers. Similarities included 1) family farm lived in diffusion of innovations. 2) economic concerns and 3) education is key while differences included perception of older folks as slow adopters. Even though the number sampled was small, N=2 for this study, the differences between the young and older age groups were characterized as "Blinding Energy" and "Earned Wisdom" respectively.

Identifying and quantifying conservation-practice adoption in U.S. cropland is key to accurately monitoring trends in soil health regionally and nationally and informing climate change mitigation efforts. We present the results of an automated system used across 645 counties in the United States Corn Belt from 2005 to 2018, mapped at field-scale and summarized for distribution at aggregated scales. Large-scale mapping by OpTIS (Operational Tillage Information System), a software tool that analyzes remotely sensed data of agricultural land, provides trends of conservation tillage (defined as >30% residue cover), cover cropping, and crop rotations, while modeling by DNDC (Denitrification–Decomposition), a process-based model of carbon and biogeochemistry in soil, provides estimates of the ecosystem outcomes associated with the changes in management practices mapped by OpTIS. Ground-truthing data acquired via OpTIS mobile, a roadside field-surveying app, were used for verification in 30 counties. OpTIS results for the Corn Belt show adoption of cover crops after planting corn and soy increased from 1% to 3% of the mapped area when comparing 2006 to 2018. Comparison of trends for conservation tillage use from 2006 to 2018 shows a slight decrease in conservation tillage adoption, from 46% to 44%. Results from DNDC show these soils sequestered soil organic carbon (SOC) at an area-weighted mean change in SOC (dSOC) rate of 161 kgC/ha/year. Comparatively, in a scenario modeled without the adoption of soil health management practices, the same soils would have lost SOC at an area-weighted rate of −65 kgC/ha/year. As many factors affect changes to SOC, including climate and initial SOC in soils, modeling counterfactual scenarios at the field scale demonstrates outcomes of current soil health management in comparison to regional management practices and best management practices, with respect to SOC sequestration. Regional trends in adoption rates of conservation agriculture and resulting soil health implications are of great use for a wide range of stakeholders. We demonstrate the capability of OpTIS remote sensing to deliver robust, large-scale, multi-sensor, ground-verified monitoring data of current and historical adoption of conservation practices, and of DNDC process-based modeling to provide assessments of the associated environmental outcomes across regions in U.S. cropland.

Soil Health plays a vital role to ensure agricultural production in a sustainable manner. The basic objective of the soil testing is to provide recommendations to the farmers for the optimum and economic use of fertilizers and better soil management practices to increase agricultural production in their farm. The present study was conducted to analyze the adoption of soil testing and Soil Health Cards for fertilizer management conducted by Krishi Vigyan Kendra (KVK), Tirur, Tiruvallur district. The data revealed that the number of conduct of awareness and training programmes on soil health management and soil samples analysed (30 nos. to 240 nos.) at KVK Tirur increased from 2012 to 2018. Results indicated that highest percentage of beneficiaries belonged to the middle age group of 36-55 years (48.75%) followed old age (37%).  Most of the farmers were practicing agriculture in Semi Medium (28%) followed by medium land holdings (24%) among the SHC beneficiaries and small (35%) and Marginal land holdings (30%) among non-SHC beneficiaries. It was observed that medium level of knowledge was obtained (48%) by SHC beneficiaries followed by high level (20%) whereas 60% of non-beneficiary was having low level of knowledge on SHC. On an average majority of the SHC beneficiary were lying in the medium adoption level (43%) followed by high adoption category (21%). Reason behind the partial adoption and no adoption might be due to their unawareness on the benefits of optimum fertilizer application. Comparative analysis between adopted beneficiaries and SHC non-beneficiaries on crop productivity in paddy, Greengram Blackgram and groundnut indicated 11.66%, 16.12%, 8.67 and 15.10% increase in productivity over non-beneficiaries.

ABSTRACT Soil microbial transformations of nitrogen (N) can be affected by soil health management practices. Here, we report in situ seasonal dynamics of the population size (gene copy abundances) and functional activity (transcript copy abundances) of five bacterial genes involved in soil N cycling (ammonia-oxidizing bacteria [AOB] amoA, nifH, nirK, nirS, and nosZ) in a long-term continuous cotton production system under different management practices (cover crops, tillage, and inorganic N fertilization). Hairy vetch (Vicia villosa Roth), a leguminous cover crop, most effectively promoted the expression of N cycle genes, which persisted after cover crop termination throughout the growing season. Moreover, we observed similarly high or even higher N cycle gene transcript abundances under vetch with no fertilizer as no cover crop with N fertilization throughout the cover crop peak and cotton growing seasons (April, May, and October). Further, both the gene and transcript abundances of amoA and nosZ were positively correlated to soil nitrous oxide (N2O) emissions. We also found that the abundances of amoA genes and transcripts both positively correlated to field and incubated net nitrification rates. Together, our results revealed relationships between microbial functional capacity and activity and in situ soil N transformations under different agricultural seasons and soil management practices. IMPORTANCE Conservation agriculture practices that promote soil health have distinct and lasting effects on microbial populations involved with soil nitrogen (N) cycling. In particular, using a leguminous winter cover crop (hairy vetch) promoted the expression of key functional genes involved in soil N cycling, equaling or exceeding the effects of inorganic N fertilizer. Hairy vetch also left a legacy on soil nutrient capacity by promoting the continued activity of N cycling microbes after cover crop termination and into the main growing season. By examining both genes and transcripts involved in soil N cycling, we showed different responses of functional capacity (i.e., gene abundances) and functional activity (i.e., transcript abundances) to agricultural seasons and management practices, adding to our understanding of the effects of soil health management practices on microbial ecology.

SummaryIn this article an on-farm monitoring approach on udder health is presented. Monitoring of udder health consists of regular collection and analysis of data and of the regular evaluation of management practices. The ultimate goal is to manage critical control points in udder health management, such as hygiene, body condition, teat ends and treatments, in such a way that results (udder health parameters) are always optimal. Mastitis, however, is a multifactorial disease, and in real life it is not possible to fully prevent all mastitis problems. Therefore udder health data are also monitored with the goal to pick up deviations before they lead to (clinical) problems. By quantifying udder health data and management, a farm is approached as a business, with much attention for efficiency, thought over processes, clear agreements and goals, and including evaluation of processes and results. The whole approach starts with setting SMART (Specific, Measurable, Acceptable, Realistic, Time-bound) goals, followed by an action plan to realize these goals.

Soil health connotes the balance of biological, physicochemical, nutritional, structural, and water-holding components necessary to sustain plant productivity. Despite a substantial knowledge base, achieving sustainable soil health remains a goal because it is difficult to simultaneously: (i) improve soil structure, physicochemistry, water-holding capacity, and nutrient cycling; (ii) suppress pests and diseases while increasing beneficial organisms; and (iii) improve biological functioning leading to improved biomass/crop yield. The objectives of this review are (a) to identify agricultural practices (APs) driving soil health degradations and barriers to developing sustainable soil health, and (b) to describe how the nematode community analyses-based soil food web (SFW) and fertilizer use efficiency (FUE) data visualization models can be used towards developing sustainable soil health. The SFW model considers changes in beneficial nematode population dynamics relative to food and reproduction (enrichment index, EI; y-axis) and resistance to disturbance (structure index, SI; x-axis) in order to identify best-to-worst case scenarios for nutrient cycling and agroecosystem suitability of AP-driven outcomes. The FUE model visualizes associations between beneficial and plant-parasitic nematodes (x-axis) and ecosystem services (e.g., yield or nutrients, y-axis). The x-y relationship identifies best-to-worst case scenarios of the outcomes for sustainability. Both models can serve as platforms towards developing integrated and sustainable soil health management strategies on a location-specific or a one-size-fits-all basis. Future improvements for increased implementation of these models are discussed.
