“…Numerous tractor-mounted remote sensors are available that might assess status of plant nutrient for present administration of spatially varying fertiliser amounts have recently become available. Commercially existing hand-held and tractor-mounted remote sensors which utilized crop reflectance information to estimate and spread over spatially variable fertiliser rates in real-time include Green Seeker, Yara N-sensor, and Crop Circle [103].…”

Emerging technologies include remote sensing, global positioning systems (GPS), geographic information systems (GIS), and the Internet of Things. The Internet of Things (IoT), Big Data analysis, and artificial intelligence (AI) are all the promising tools that are being used to solve complications, improve agricultural operations, and reduce expenses. Satellite remote sensing has been indispensable in understanding Earth and atmospheric dynamics over the last five decades. When compared to ground or aerial sensor acquisitions, satellite sensors have the ability to provide data at global sizes at a lower cost. With the support of satellite remote sensing, the scientific community has attained significant progress in recent years. In consideration of these efforts, the current study is intended to provide a comprehensive review of the function of remote sensing in assessing different water security challenges and other purposes. Crop production forecasting, drought assessment, cropping system analysis, horticultural assessment and development, crop development, thorough site analysis, satellite agro-meteorology, precision farming, crop insurance, and other operational big agricultural applications are examples. This research examines various uses as well as potential gaps in the market.

“…However, the continuously enhanced use of agricultural inputs (e.g., fertilizer and pesticide) could lead an environmental degradation, including the depletion of natural resources, polluted surface water and underground flows, and eutrophication ( Kleinman et al, 2011 ; Konikow, 2015 ; Sishodia et al, 2017 ). Moreover, the over and/or inefficient use of water, fertilizers, pesticides, and herbicides for potato crops over the growing season causes economic losses and negative impacts on the environment ( Hendricks et al, 2019 ). To constantly and sustainably meet the increasing needs for potato production, reducing environmental losses with improved potato productivity is the key topic in precision agricultural activities for potatoes ( Delgado et al, 2019 ).…”

Potato is one of the most significant food crops globally due to its essential role in the human diet. The growing demand for potato, coupled with severe environmental losses caused by extensive farming activities, implies the need for better crop protection and management practices. Precision agriculture is being well recognized as the solution as it deals with the management of spatial and temporal variability to improve agricultural returns and reduce environmental impact. As the initial step in precision agriculture, the traditional methods of crop and field characterization require a large input in labor, time, and cost. Recent developments in remote sensing technologies have facilitated the process of monitoring crops and quantifying field variations. Successful applications have been witnessed in the area of precision potato farming. Thus, this review reports the current knowledge on the applications of remote sensing technologies in precision potato trait characterization. We reviewed the commonly used imaging sensors and remote sensing platforms with the comparisons of their strengths and limitations and summarized the main applications of the remote sensing technologies in potato. As a result, this review could update potato agronomists and farmers with the latest approaches and research outcomes, as well as provide a selective list for those who have the intentions to apply remote sensing technologies to characterize potato traits for precision agriculture.

“…La aplicación excesiva de fertilizantes minerales (de síntesis química) en algunos casos es justificada por los agricultores ante eventos climáticos extremos, como es el caso de los huracanes, en los que la alta precipitación lixivia los nutrientes del suelo (Hendricks et al 2019). Sin embargo, en general, una sobrefertilización de los suelos, así como una fertilización limitada, se consideran prácticas no deseables por las consecuencias negativas para el medio ambiente, así como por la reducida eficiencia económica (Sadeghpour et al 2017), además del decremento de la biodiversidad y la degradación de los suelos (Díaz et al 2016).…”

Fertigation allows fertilizers to be supplemented at the required time and place, increasing their use efficiency. The present study determined whether the amount of mineral fertilizers applied to squash can be reduced, compared to the recommended dose, by fractioning their application through a fertigation system. Three treatments were designed: 100% of the recommended dose (120-33.6-174.3 kg ha -1 N-P-K) applied in solid form at sowing, and 62.5% and 50% of the control treatment, but with a split application through the growing season. Neither the fruit yield nor the concentration of N, P, Ca, and Mg in the shoot were affected when the dose was reduced to 62.5% or 50%; however, the plants showed greater efficiency in the recovery of N and P and greater ag- ronomic efficiency per unit of N, P and K applied. In conclusion, fractionated fertilization applied through fertilgation reduces the fertilization dose without affecting the squash yield or growth due to an increase in both the recovery and agronomic efficiencies of the applied nutrients.
