“…Conservation tillage could have some environmental benefits and indirect effects on water pollution [26,44]. The increase of soil organic content permits decreasing the carbon oxide emissions and having a greater energetic efficiency [36]. In this study, a preliminary grey WF assessment on the field dataset is made to understand the effects of conservation tillage and precision agriculture on water pollution.…”

“…The variable rate application differs among four different homogeneous zones (Figure 1a). The homogenous zones are identified using the Salus model in a map of prescription as homogenous areas of soil spatial variability of soil productive potential [13,36]. The Salus model is designed to simulate crop production under different soil management, simulating the dynamics of nutrients with different atmospheric and soil conditions [34].…”

Increasing global food demand and economic growth result in increasing competition over scarce freshwater resources, worsened by climate change and pollution. The agricultural sector has the largest share in the water footprint of humanity. While most studies focus on estimating water footprints (WFs) of crops through modeling, there are only few experimental field studies. The current work aims to understand the effect of supposedly better agricultural practices, particularly precision agriculture (variable rate application of fertilizers and pesticides) and conservation agriculture (minimum, strip, or no-tillage), on water deterioration and water pollution. We analyzed the results from an experimental field study in the northeast of Italy, in which four different crops are grown across three years of crops rotation. We compared minimum, strip, and no-tillage systems undergoing variable to uniform rate application. Grey WFs are assessed based on a field dataset using yield maps data, soil texture, and crop operations field. Leaching and associated grey WFs are assessed based on application rates and various environmental factors. Yields are measured in the field and recorded in a precision map. The results illustrate how precision agriculture combined with soil conservation tillage systems can reduce the grey water footprint by the 10%. We assessed the grey Water Footprint for all the field operation processes during the three-year crop rotation.

“…Three-year historical production maps in conjunction with σ a mapping are used by Cillis et al [10] to determine homogeneous zones. Analysis is conducted using electrical conductivity, characteristics related to soil upper portion (0 cm-50 cm) and related to the roots of corn (Zea mays L.), soybean [Glycine max (L.) Merr.]…”

Root System Analysis and Influence of Moisture on Soil Electrical Properties

This paper proposes a methodology for plant root system and soil moisture analysis through the geoelectrical prospecting method. Overall, bench and field experiments are implemented to analyze the behavior of electrical conductivity of the soil in relation to moisture content and plant root system growth. Specifically, Wenner array and lateral profiling technique are used to stratify the soil in horizontal layers, performing in-depth analysis. Millet (Pennisetum glaucum L.), bean (Phaseolus vulgaris L.) and sorghum (Sorghum bicolor L. Moench) are used to analyze the root system behavior. Results show that the soil water dynamics can be observed through soil stratification in horizontal layers and the plant root system is correlated with apparent electrical conductivity of the soil. Thus, geoelectric prospecting methods can be used as an analysis tool, both of soil moisture dynamics and of plant roots, to support decision making regarding soil and crop management.

“…Much activity is carried on new machinery [3] and in general on new equipment, which can be integrated on agricultural implements and vehicles [4]. A lot of efforts are spent in particular on new sensors [5,6], which have the potential to allow frequent monitoring [7], automation of operations and support to the decision making process [8]. Research is also done for the development of new highly performing materials, especially with biodegradable properties [9], in accordance with a common attention for the environment [10].…”

“…Research is also done for the development of new highly performing materials, especially with biodegradable properties [9], in accordance with a common attention for the environment [10]. The growing attention on environment [11][12] has brought noticeable drawbacks in the development or evolution of treatments with sustainable management approaches [13], optimized treatments and fertilizers distributions [7,14], organic productions and in general products, which are less impacting on soil, air and water [15][16][17]. Reduction of impacts passes through the optimization of energy resources: many works have been recently done to find new resources [18; 19] and to minimize energy consumptions related to different agricultural processes [20].…”

Inventions play an important role in all sectors of our society, including the agricultural sector. As they have played an essential role in the development of our agricultural system in the past, inventions can and should be of importance as a driver for innovations towards sustainable development of agriculture in the future. The present paper analyses the current status of agricultural and bioresource engineering patents, with the aim to define the current trends and potentials of agricultural engineering. The research takes advantage of the EspaceNet patent database, which has indexed more than 38900 patents in agricultural engineering since the beginning of the century. The analysis starts from a selection of most recurrent words in this database, and proposes a clusterization in thematic groups. Then, comparisons are carried out both on thematic groups and on single terms, in order to determine trends, recognise correlations, and eventually identifying most strategic areas. The results highlight a growing attention on machinery, on data and automation, while lower relevance is progressively covered by chemical treatments. Specifically, a clear relevance is noticed on agricultural vehicles and implements, on irrigation systems and on greenhouses.
