Compost for soil application and compost for growing media
2016
Blok, C.
Soil properties of importance are dry bulk density, organic matter content, nutrient content and waterholding capacity.Rooting media properties of importance are pH, EC, water retention, water uptake rate, porosity, stability,shrinkage and nitrogen fixation.Miscommunication between producers and user groups can be avoided by measuring the relevantproperties using methods users are familiar with.Special attention is needed to interpret total nutrients, extracted nutrients and organic matter content.

Afficher plus [+] Moins [-]Growing degree hours - a simple, accurate, and precise protocol to approximate growing heat summation for grapevines Texte intégral
2016
Gu, S.
Despite its low accuracy and consistency, growing degree days (GDD) has been widely used to approximate growing heat summation (GHS) for regional classification and phenological prediction. GDD is usually calculated from the mean of daily minimum and maximum temperatures (GDDₘₘ) above a growing base temperature (T gb). To determine approximation errors and accuracy, daily and cumulative GDDₘₘ was compared to GDD based on daily average temperature (GDDₐᵥg), growing degree hours (GDH) based on hourly temperatures, and growing degree minutes (GDM) based on minute-by-minute temperatures. Finite error, due to the difference between measured and true temperatures above T gb is large in GDDₘₘ but is negligible in GDDₐᵥg, GDH, and GDM, depending only upon the number of measured temperatures used for daily approximation. Hidden negative error, due to the temperatures below T gb when being averaged for approximation intervals larger than measuring interval, is large in GDDₘₘ and GDDₐᵥg but is negligible in GDH and GDM. Both GDH and GDM improve GHS approximation accuracy over GDDₘₘ or GDDₐᵥg by summation of multiple integration rectangles to reduce both finite and hidden negative errors. GDH is proposed as the standardized GHS approximation protocol, providing adequate accuracy and high precision independent upon T gb while requiring simple data recording and processing.

High-quality soil cultivation for potato planting increases its productivity and allows to reduce damageability of tubers when harvesting. At its growing intensive complete or strip soil pulverizationl, formation of ridges or seedbeds for planting and growing are required. For performance of each method machines of different type, including various tillers, tilling ridge or seedbed formers, are used. The authors offered a multipurpose tiller with the horizontal rotor aggregated with tractors of classes 1.4 and 2. At readjustment the tiller operatest the main methods of soil cultivation necessary at potato growing: complete prelanding tilling, ridges or seedbeds formation for planting, cultivation of them at care of seedlings, loosening of an underlying layer in strips of the formed ridges or seedbeds under planting rows. This tiller has some constructional features: the tiller rotor with removable sections of flat L-shaped teeths allowing to operate complete and strip soil cultivation at a depth of 12 cm; the disk furrow shaperы regulated on depth and operating width; removable hoes for loosening of the lower layer of soil at depth of 22 cm under planting rows; a replaceable deflector with a direct back edge and (or) with a removable furrow shapers; basic wheels movable from a forward girder onto sidewalls behind - when seedbeds forming. The authorsreport the main agrotechnical requirements to the methods of complete prelanding tilling, ridges and seedbeds forming which are carried out by a tiller and cultivation of them when planting. The tiller has different complete set options for performance of these methods. Use of the offered tiller provides high-quality performance of methods of soil cultivation and potato growing and by 2-3 times reduces a range of necessary machines and costs of acquisition of them.

Afficher plus [+] Moins [-]Method for Evaluation of Soil Conditions Suitable for Growing Emmer and Einkorn Wheat Texte intégral
2016
Mitreva, Zornitsa | Krasteva, Veneta | Pankov, Veselin
Method is developed for the field rating of main soil characteristics that define the suitability for growing emmer and einkorn wheat. Soil texture of the fallow land, depth of the humus horizon, depth of the soil profile, texture differentiation of the soil profile, soil reaction, humus content and groundwater level have been evaluated. The method is harmonized with the officially accepted in Bulgaria parametric methods of the system of field ratings and the categorization of the agricultural lands. The end result is an evaluation of the soil conditions and a soil rating.

Περιέχει βιβλιογραφικές παραπομπές. | Στόχος της παρούσας μελέτης είναι να αναδείξει τον ρόλο των ανθρωπίνων πόρων σε μια επιχείρηση, τους παράγοντες οι οποίοι επιδρούν στους ανθρώπινους πόρους αλλά και το πώς αυτοί με τη σειρά τους επηρεάζουν το εργασιακό περιβάλλον. Πιο συγκεκριμένα, το πως τα άυλα χαρακτηριστικά των επιχειρήσεων όπως η επικοινωνία, οι συμπεριφορές, οι αξίες, η ηθική μπορούν να διαμορφώσουν ένα αποτελεσματικό και αποδοτικό εταιρικό περιβάλλον. Την πρωταρχική σημασία της λειτουργίας του ανθρώπινου παράγοντα ως μοχλού ανάπτυξης ή ύφεσης μιας επιχείρησης. Τους τρόπους με τους οποίους μπορεί να καλλιεργηθεί το ομαδικό κλίμα συνεργασίας μεταξύ των εργαζομένων με στόχο την επίτευξη των εταιρικών στόχων. Τη σημασία και τη σπουδαιότητα της διαδραστικής σχέσης που υφίσταται ανάμεσα στην επιχείρηση και τους εργαζομένους που την συνιστούν. Στο πρώτο κεφάλαιο γίνεται μια προσέγγιση της στρατηγικής προγραμματισμού των ανθρωπίνων πόρων, ώστε να αναλυθούν τα τεχνικά χαρακτηριστικά που θα πρέπει να λαμβάνει υπόψη της η επιχείρηση για έναν επιτυχημένο προγραμματισμό. Στο δεύτερο κεφάλαιο γίνεται ανάλυση του κοινωνικού κεφαλαίο και εξετάζονται τα θέματα των ανθρωπίνων αναγκών, η σημασία των αποτελεσματικών ομάδων, ο ρόλος του ηγέτη και τα είδη ηγεσίας. Στο τρίτο κεφάλαιο αναλύονται τα κίνητρα που μπορούν να ενεργοποιήσουν και να μεγιστοποιήσουν την παραγωγικότητα και την αποτελεσματικότητα του ανθρώπινου παράγοντα, όπως η επιχειρηματική ηθική, η δύναμη, η εξουσία και οι πολιτικές διεργασίες του εταιρικού οργανισμού. Στο τέταρτο και τελευταίο κεφάλαιο, με άξονα τη μελέτη περίπτωσης της εταιρίας λειτουργίας αυτοκινητοδρόμων «Ολυμπία Οδός», αναλύεται ο βαθμός εργασιακής ικανοποίησης των εργαζομένων της ως προϊόν της εταιρικής κουλτούρας που προωθεί η εταιρία. Η ερευνητική μέθοδος που ακολουθήθηκε για την εξαγωγή συμπερασμάτων αναφορικά με το παραπάνω ζητούμενο ήταν μέσω δομημένων ερωτηματολογίων που απαντήθηκαν από το προσωπικό της εταιρίας. Στο πρώτο ερωτηματολόγιο οι εργαζόμενοι κλήθηκαν να αξιολογήσουν το είδος της εταιρικής κουλτούρας ενώ στο δεύτερο κλήθηκαν να αξιολογήσουν το βαθμό στον οποίο η εταιρική κουλτούρα δύναται να παράγει ένα υψηλό επίπεδο εργασιακής ικανοποίησης. | The present study aims at highlighting the role of human resources in a company, the factors which affect the human resources and respectively how human resources can influence the work environment. More specifically, it presents the way in which the non-material traits of the companies, i.e. communication, attitudes, values and ethics, can form an efficient and effective business environment; the essence of the human factor as the driving force of a company’s growth or recession; the ways in which team spirit can be cultivated among the employees, so that company goals can be achieved; the sense and significance of the interactive relation developed between the company and its employees. Chapter 1 presents an approach to the human resources strategic planning, in order to analyze the technical characteristics that a company should take into consideration in order to obtain a successful planning. Chapter 2 presents an analysis of the social capital and reviews the issues of human needs, the significance of effective teams, the role of the leader and the types of leadership. Chapter 3 illustrates the motives that can activate and maximize the productivity and effectiveness of the human factor, such as business ethics, status, power and political processes of the company. The final chapter presents the case study of the motorway operation company “Olympia Odos”: the work satisfaction of its employees is analysed, as the outcome of business culture that the company promotes. The research method followed in order to draw conclusions on this query was based on structured questionnaires, which were filled in by company personnel. In the first questionnaire the employees were asked to evaluate the kind of business culture prevailing in the company, whereas in the second questionnaire they were asked to evaluate the extent to which the business culture may invoke a high level of work satisfaction.
