AB  - In Serbia, there are about 400.000 hectares of heavy mechanical composition soil and over 100.000 hectares of soil damaged in 
various ways. Every year, with different degradation processes, new 1.000 hectares of soil are damaged. From the aspect of physical 
properties, soil compaction represents a serious problem that leads to changes in physical-mechanical and water-air properties and is one of 
the main factors of soil degradation. This paper presents the technique of measuring soil compaction on experimental field of 1 hectare using 
a hand-held penetrometer on operating depth 25cm, along with the geographic location of the sampling points. The data obtained in this 
research, the method of collecting, processing and displaying that data suggested certain shortcomings of the application of this method for 
testing soil resistance, as well as the need for a procedure for measuring soil resistance using a continuous method.

AB  - Посредством предложеног новог техничког решења омогућава се постављање спектрометријских сензора на платформу која се потом агрегатира и прикључује на трактор у три тачке помоћу његовог подизног механизма. Доње прикључне тачке платформе везане су за рамску конструкцију платформе помоћу четири завртањске везе и могуће је подешавање њиховог међусобног растојања у хоризонталном правцу. На крила платформе се може поставити различит број сензора. Могуће је подешавање размака између њих. Средње крило налази се на вертикалним вођицама, те се његовим вертикалним кретањем подешава растојање између сензора и усева. Два бочна крила платформе везана су зглобном везом за средње. У транспортном положају бочна крила се подижу вертикално, а у радном положају се спуштају у радни положај и имају распон 6410 mm.

AB  - When preparing a crop scouting mission using UAS, two parameters are set: flight altitude and overlap of images. In practice, crop scouting is most often done at altitudes of 70 to 100 meters, and the switchover is most often between 50 and 100%. The research question that is dealt with in this paper is whether there is a significant difference in the obtained light reflection indexes and consequently postprocessed vegetation indexes, depending on height and overlap. The flight height of the UAS dictates spatial resolution, and the switching dictates the time resolution of the 
reconnaissance. The research was carried out on the experimental plot of barley. The missions were consecutive and performed in perfect weather conditions. The sky was clear, and the light was approximately uniform during all missions with variable heights and overlaps.

AB  - This paper presents different methods for detecting changes in the condition of crops and making a special contribution through the presentation of modeling a tractor platform for crop scouting. This platform was designed in the APS LAB laboratory at the Faculty of Mechanical Engineering in Belgrade intended for the placement of spectrometric sensors. The choice of a suitable method or algorithm for the desired crop scouting is crucial for the success of further analysis of the obtained 
data. Four modes of spectrometry are presented. Beside handheld sensors, there are described methods of data capture via drones and satellites. Most of this paper belongs to the use of sensors in the composition of agricultural machines. This type of scouting is the most effective when it is carried out simultaneously with the distribution of mineral nutrients and crop protection. The tractor platform, on which the sensors are located, can be either a worn type or a connecting type that allows connection to a tractor in three-point in the conventional way. Except for the aforementioned ways, the sensors can be placed on the roof of the tractor or directly on the working machines. 
The process of constructing and modeling the front tractor platform is presented in detail in Solid Works program. Apart from the construction shown, there is a possibility of changing the platform. All foreseen and feasible variants are presented in this paper.

AB  - Pri merenju i analizi lokacijski specifičnog prinosa poznatijeg kao monitoring prinosa u okviru šireg ciklusa precizne poljoprivrede meri se oko 30 parametara od interesa za mapiranje prinosa i šire. Najvažniji parametri uz podrazumevana tri parametra koja definišu lokaciju (latituda, longituda i elevacija) su maseni prinos zrna i vlažnost zrna. Uz ove podatke tokom monitoringa prinosa u ovom radu posmatrani su i temperatura zrna, brzina kretanja kombajna i odstupanje preciznosti lociranja (DOP). Jednostavnim statističkim testiranjem korelacije između ovih parametara utvrđen je nivo međusobnog uticaja, između ostalog i stepen uticaja svih navedenih i posmatranih parametara na prinos, kao odgovor na istraživačko pitanje da li na prinos utiče još neki parametar osim lokacije i fizičko-hemijskih osobina zemljišta na toj lokaciji. Utvrđen je različit stepen uticajnosti, ali nije otkriven ni jedan značajan dodatni uticaj na prinos izračunat posredstvom merenja i makon samog merenja. Za monitoring prinosa pri žetvi semenske pšenice na imanju 'Mladost' PKB, Tabla 2, korišćen je kombajn Class Lexion 450 sa nadograđenim sistemom za monitoring AGL Technology proizvođača.

AB  - When measuring and analyzing site-specific yield known as the yield monitoring within a wider cycle of precise agriculture, about 30 parameters are measured from inertia for mapping yields. The most important parameters with the default three parameters that define the location (latitude, longitude and elevation) are mass grain yield and grain moisture. In addition to this data during the yield monitoring, the temperature of the grain, speed of the combine and delution of precision (DOP) were also observed in this paper. By simple statistical testing of the correlation between these parameters, the level of mutual influence was determined, among other things, the degree of influence of all mentioned and observed parameters on yield, in response to the research question whether the yield affects another parameter other than the location and physical and chemical properties of the land at that location . A different degree of influence was determined, but no significant additional impact on the yield was calculated by measuring and measuring the measurement itself. For the monitoring of the yield of seed wheat harvesting on the 'Mladost' PKB, Tabla 2, the Class Lexion 450 harvester with an upgraded system for monitoring the AGL Technology manufacturer was used. For the statistical analysis, the parametric method of correlation within the software package SPSS Statistics v.21 was used.
