“…For example, the overall finding that continuous soil cover can improve infiltration rate is corroborated by prior research focused on cover crops or agroforestry. A recent meta-analysis of eight experiments in Argentina found a similar effect of cover crops on infiltration rate, where infiltration was increased by an average of 36% due to the presence of cover crops compared to no cover controls 70 . Also, Ilstedt et al 71 found that afforestation and agroforestry increased infiltration rates relative to annual crop systems by 100-400% across four experiments in tropical agroecosystems.…”

20 Identifying agricultural practices that enhance water cycling is critical, particularly with 21 increased rainfall variability and greater risks of droughts and floods. Soil infiltration rates offer 22 useful insights to water cycling in farming systems because they affect both yields (through soil 23 water availability) and other ecosystem outcomes (such as pollution and flooding from runoff).24 For example, conventional agricultural practices that leave soils bare and vulnerable to 25 degradation are believed to limit the capacity of soils to quickly absorb and retain water needed 26 for crop growth. Further, it is widely assumed that farming methods such as no-till and cover 27 crops can improve infiltration rates. Despite interest in the impacts of agricultural practices on 28 infiltration rates, this effect has not been systematically quantified across a range of practices. To 29 evaluate how conventional practices affect infiltration rates relative to select alternative practices 30 (no-till, cover crops, crop rotation, introducing perennials, crop and livestock systems), we 31 performed a meta-analysis that included 89 studies with field trials comparing at least one such 32 alternative practice to conventional management. We found that introducing perennials (grasses, 33 agroforestry, managed forestry) or cover crops led to the largest increases in infiltration rates 34 (mean responses of 59.2 ± 20.9% and 34.8 ± 7.7%, respectively). Also, although the overall 35 effect of no-till was non-significant (5.7 ± 9.7%), the practice led to increases in wetter climates 36 and when combined with residue retention. The effect of crop rotation on infiltration rate was 37 non-significant (18.5 ± 13.2%), and studies evaluating impacts of grazing on croplands indicated 38 that this practice reduced infiltration rates (-21.3 ± 14.9%). Findings suggest that practices 39 promoting ground cover and continuous roots, both of which improve soil structure, were most 40 effective at increasing infiltration rates. 41 3 42 Introduction 43There is a need to develop more resilient, multifunctional agricultural systems, 44 particularly given risks posed by climate change to farm productivity and environmental 45 outcomes 1,2,3 . Specifically, water-related risks from increased rainfall variability include soil 46 erosion and water pollution, degradation of soil quality, and reductions to crop yields 4,5,6 .47 Although soils are vulnerable to water-related risks, they are also being recognized as a medium 48 to mitigate such risk when managed to deliver a wide range of ecosystem benefits, beyond 49 maximizing crop production 7,8 . Thus, designing agricultural systems that improve soils and soil 50 water cycling is one strategy that could help reduce negative impacts of increasing rainfall 51 variability 9,10,11,12 . To this point, global modeling analyses indicate that enhancing soil water 52 storage at a large scale can benefit crop productivity and improve ecosystem services, such as by 53 reducing runoff 13,14 . However, ther...

Field studies have been performed for decades to analyze effects of different management practices on agricultural soils and crop yields, but these data have never been combined together in a way that can inform current and future cropland management. Here, we collected, extracted, and integrated a database of soil health measurements conducted in the field from sites across the globe. The database, named SoilHealthDB, currently focuses on four main conservation management methods: cover crops, no-tillage, agro-forestry systems, and organic farming. These studies represent 354 geographic sites (i.e., locations with unique latitudes and longitudes) in 42 countries around the world. The SoilHealthDB includes 42 soil health indicators and 46 background indicators that describe factors such as climate, elevation, and soil type. A primary goal of this effort is to enable the research community to perform comprehensive analyses, e.g., meta-analyses, of soil health changes related to cropland conservation management. The database also provides a common framework for sharing soil health, and the scientific research community is encouraged to contribute their own measurements.

“…Tanaman penutup tanah adalah salah satu dari beberapa praktek pertanian berbasis alam yang paling dikenal dapat meningkatkan penyediaan berbagai layanan ekosistem di agroekosistem (Keesstra et al, 2018). Residu tanaman penutup tanah diketahui dapat memberikan efek baik pada intensitas dan variabilitas musiman dari berbagai proses tanah yang relevan dengan transportasi dan transformasi hara dalam tanah (Kahimba et al, 2008;Siczek and Lipiec, 2011;Alvarez, 2017;Daryanto et al, 2018). Tanaman penutup tanah telah lama diakui sebagai praktek yang bermanfaat tidak hanya karena dampaknya terhadap penurunan erosi tanah dan hilangnya hara tanah (Asbur et al, 2016;Alvarez et al, 2017;Snapp and Surapur, 2018;Hanrahan et al, 2018), tetapi juga untuk pengendalian gulma (Alonso-Ayuso et al, 2018), meningkatkan aktivitas mikroorganisme tanah (Nevins et al, 2018), dan penambahan bahan organik tanah (Asbur dan Ariyanti, 2017).…”

Studi jarak tanam dan naungan terhadap pertumbuhan dan potensi Asystasia gangetica (L.) T. Anderson sebagai tanaman penutup tanahStudy of plant distance and shade on growth and potential of Asystasia gangetica (L.) T. Anderson as cover crop Abstract. Cover crop is one of nature-based agricultural practices that can increase the provision of various ecosystem services in agroecosystems. A. gangetica is a weed that is often found in oil palm plantations and has the potential as a cover crop. This study aimed to study the optimum planting distance of growth and potential of A. gangetica as a cover crop on open and shaded land. The study was conducted at the Experimental Field, Faculty of Agriculture, UISU, Medan, from January to April 2018. The study used a Split Plot Design with three replications. The first factor as main plot was shade that consisted of two levels, there were: without shade and 50% shaded. The second factor as subplot was planting distance which consisted of three levels, there were: 10 cm x 10 cm, 20 cm x 20 cm, and 40 cm x 40 cm. The results showed that A. gangetica has the potential as cover crop because it grew fast, cover land rapidly, adapt to the environment, and able to suppress weed with an optimum planting distance of 20 cm x 20 cm.
