“…In a parallel trial conducted in glasshouse, the authors of the present trial (Coelho et al 2019a) found very similar plant growth responses of ryegrass to the application of different types of anaerobic digestates, where comparable yields were obtained by different anaerobic digestates equally balanced in terms of dry matter and plant growth responses were highly associated with the input amounts of NPK. In the literature, the fertilisation effect of anaerobic digestates on grass growth has been reported to have a strong link with the total amount of N applied and its availability (NH 4 + ) in the digested solution (Gunnarsson et al 2010;Andruschkewitsch et al 2013;Fouda et al 2013;Walsh et al 2018); indeed, grass growth responses are in general also strongly associated with N amount and availability (Bryant et al 2012;Foito et al 2013).…”

“…Higher levels of available P and K found in soils treated with the biofertilisers compared with the controls with CAN and no fertiliser can be considered a natural consequence of the repeated applications of these nutrients via biofertilisation (Table 2). In the parallel trial conducted with the same anaerobic digestates in a glasshouse trial with ryegrass, white clover and bare soils, the authors of this work found increases in the soil available P and K due to anaerobic digestates applications (Coelho et al 2019a). The quantities of available soil P are associated with P inputs via fertilisation (Oehl et al 2002;McLaughlin et al 2011;Kalidas-Singh and Thakuria 2018).…”

“…grasses), the plant growth effects of anaerobic digestates have been reported to match or even exceed the performance of other traditional inorganic and organic fertilisers (Gunnarsson et al 2010;Bougnom et al 2012;Walsh et al 2012;Andruschkewitsch et al 2013;Walsh et al 2018), which has attracted interest in their use. The main fertiliser effects of anaerobic digestates are generally reported due to their concentrations of high amount of N and its plantavailable form of ammonium (NH 4 + ), as well as the concentrations of other plant nutrients (Alburquerque et al 2012;Möller and Müller 2012;Johansen et al 2013;Nkoa 2014;Coelho et al 2019a). Nevertheless, since there is much variability between physical-chemical compositions in the different types of anaerobic digestates being produced (Coelho et al 2018) and also the presence of complex microbial communities, including microbes with possible roles in plant growth biostimulation and soil nutrient cycling (e.g.…”

This study investigated how repeated applications of different types of anaerobic digestates and undigested cattle slurry affected the growth responses and nutritional aspects of ryegrass swards (Lolium perenne L.) and soil nutrient concentrations, in a twoseason field trial. The treatments included four different types of anaerobic digestate, undigested cattle slurry, nitrogen control (Ncontrol) with calcium ammonium nitrate (CAN) and a no fertiliser control, distributed in a randomised block design with three replicates. The different types of biofertilisers drove a comparable average forage daily growth rate varying between 65 and 79 kg ha −1 day −1 (p > 0.05). Crude protein and neutral or acid detergent fibre of the forage were not influenced by any type of biofertiliser (p > 0.05). Most of the anaerobic digestates led to increases in the level of soil available P and K (p < 0.05). Despite the detectable influence of the levels of NPK in the biofertilisers on the plant growth responses, different anaerobic digestates when applied using the same dry matter amounts can drive comparable forage grass growth responses with low influence over the nutritional quality of the ryegrass forage. Repeated applications of anaerobic digestates can help to increase or reduce the losses of the soil available P and K. The application of anaerobic digestate, cattle slurry and calcium ammonium nitrate led to increases in the N content of the soil; however, there were no differences between them, despite their considerable differences in terms of N inputs. This might be linked to the volatility and losses of the readily available N from the biofertilisers applied.

“…Concurrently, the UAV was utilized to capture the corn plants' reflectance information from which the NDVI levels were generated. The NPKC macronutrient compositions in soil samples were analyzed and determined using the widely reliable and applied ICP-OES (Inductively Coupled Plasma -Optical Emission Spectrometry) method with the guidelines from the Syngistix ICP model (Perkins Elmer Optima 8000, Germany) [30][31][32].…”

Fertilizer misapplications have induced widespread environmental deteriorations, climatic catastrophes, and economic losses; meanwhile, the Precision Agriculture (PA) endorsements have been influential in alleviating these issues. This study intended to tackle the fertilizer consumption inefficiencies by utilizing non-destructive remote sensing technologies, soil macronutrient distribution analysis, and a deep learning model. Specifically, an Unmanned Air Vehicle (UAV) was used in a cornfield to capture the plant's reflectance information for retrieving the Normalized Difference Vegetation Index (NDVI) during the vegetative and reproductive growth stages. Consequently, the field's soil samples were examined for their Nitrogen, Phosphorus, Potassium, and Carbon (NPKC) macronutrient constituencies. Finally, a Convolutional Neural Network-Regression model was developed to predict infield NPKC spatiotemporal variations in soil using the NDVI measurements. The deep learning model effectively determined the surpluses or shortages of the NPKC macronutrients within the cornfield throughout the growth stages. The model performed vigorously with R 2 values of 0.93, 0.92, 0.98, and 0.83 in predicting N, P, K, and C levels in soil, respectively.

“…In artificial cultivation, the mixed planting method of leguminous and gramineous plants is usually adopted to build grassland. Compared with monoculture grassland, the mixed planting of grassland not only has advantages in improving forage yield and quality [5][6][7] but also plays an obvious role in improving soil fertility and realizing systematic sustainable production [8]. In a grazing experiment in Canada, Chen et al [9] found that total amounts of N 2 fixed in Medicago sativa and Poa pratensis mixed pastures were sufficient to replace N fertilizer and sustain plant protein for grazing compared with grass-only pastures.…”

In artificial ecosystems, mixed planting of gramineous and leguminous plants can have obvious advantages and is very common. Due to their improved growth performances and stress tolerance, endophyte-infected grasses are considered to be ideal plant species for grasslands. However, endophytic fungi can inhibit the growth of neighboring nonhost leguminous plants. In this study, we chose endophyte-infected and endophyte-free tall fescue (Lolium arundinaceum Darbyshire ex. Schreb.) and clover (Trifolium repens) as the experimental materials to explore whether arbuscular mycorrhizal fungi and rhizobium can alleviate the inhibitory effect of endophyte infection on clover. The results showed that endophytic fungi significantly reduced clover biomass. Arbuscular mycorrhizal fungi inoculation significantly increased the biomass of clover in both endophyte-infected tall fescue/clover and endophyte-free tall fescue/clover systems but the beneficial contribution of arbuscular mycorrhizal fungi was more obvious in the endophyte-infected tall fescue/clover system. Rhizobia inoculation could alleviate the detrimental effect of tall fescue on the growth of clover but did not alleviate the detrimental effect of endophyte infection on the growth of clover.
