The forest as main fighting element against soil degradation and pollution is the larger gift that nature could offers to the human being, continuing to be a great miracle even for the greatest specialists. A modern democracy, cannot be consolidate without having the private propriety as main background which is the result of hard work and life saving, due to which the main goal of the human being is to improve its life conditions. The paper shows up a technical documentation for measuring and identification of forest situated on administrative territory of GIROC, TIMIS county. The purpose of the paper consist in registering the forest area into the Land Register Book according to the owners name by applying the 247/2005 law. The whole area is covered by forest vegetation. The 61.90 ha of oak forest, is having a medium density of 4m, the trees height is around 12 m, and the average thick is 0.25m. The forest is situated nearby Timiseni Monastery at the territorial administrative boundary between Sag and Giroc district. The work beneficiary: Timisoara Archbishopric, Saraca Monastery. The work purpose: consist in identification and field measurements in order to land register the woods parcels Pd420, Pd425, Pd425, Pd411, Pd407, Pd408 in the Timisoara Archbishopric propriety, on the territorial administrative territory of Giroc. Concerning the juridical situation of the propriety, for the moment this is part of the Committee of Propriety Laws for the propriety restitutions, of Giroc Council, Timis County. The topographical field measurements were achieved by using TRIMBLE 5503 DR total station. The projecting system used is Stereographic 70 projecting system.The data acquired by the field measurements, was processed by GEOTOP- Odorheiu Secuiesc software, TOPOSYS 5.1.
森林作为对抗土壤退化和污染的主要因素,是大自然给予人类的更大礼物,即使对最伟大的专家来说,它仍然是一个伟大的奇迹。现代民主的巩固离不开私有制作为主要背景,私有制是辛勤劳动和节约生活的结果,因此人类的主要目标是改善其生活条件。本文提出了一份测量和鉴定位于TIMIS县GIROC行政领土上的森林的技术文件。该文件的目的是通过适用247/2005法律,根据所有者名称将森林区域登记到土地登记册中。整个地区被森林植被覆盖。61.90 ha的栎林,中等密度为4m,树高约12 m,平均厚度为0.25m。森林位于萨格区和吉洛克区之间领土行政边界的蒂米塞尼修道院附近。工作受益人:蒂米什瓦拉大主教区,萨拉卡修道院。工作目的:包括鉴定和实地测量,以便在Giroc领土行政领土上的蒂米什瓦拉大主教辖区内对Pd420、Pd425、Pd425、Pd411、Pd407、Pd408林地进行土地登记。关于财产的法律情况,目前这是蒂米斯县吉洛克委员会财产赔偿法律委员会的一部分。地形现场测量采用TRIMBLE 5503 DR全站仪。所使用的投影系统为立体70投影系统。野外测量所得数据,采用GEOTOP- Odorheiu Secuiesc软件TOPOSYS 5.1进行处理。

This study seeks to review the effects of fertilizer residues in soils and on crop performance in the savanna agro-ecological zone of northern Nigeria. Studies conducted in some parts of northern Nigeria revealed that there are residual effects of fertilizers on soils and they significantly affect crop performance. The annual applications of nitrogen, phosphorus and potassium over the years significantly affected exchangeable cations and consequently crop yields. As the fertilizer rates are increased, the efficiency of fertilizer nutrient use decreases, leaving behind in the soil an increasing proportion of the added nutrients. This is more prominent in the savanna zone where rainfall is generally inadequate and the rate of weathering is high. Hence, when nutrient content of the soil is already sufficient, adding fertilizer to the soil is likely to be damaging to both the soil and the crop. Consequently, the use of organic and inorganic fertilizers in the savanna zone of northern Nigeria should be base on specific soil diagnoses to determine the need for adding nutrients.
本研究旨在回顾尼日利亚北部热带稀树草原农业生态区土壤中肥料残留物及其对作物生产性能的影响。在尼日利亚北部一些地区进行的研究表明,化肥对土壤有残留影响,严重影响作物生产。多年来,氮、磷和钾的年度施用显著影响了交换阳离子,从而影响了作物产量。随着施肥量的增加,肥料养分利用效率降低,在土壤中留下的添加养分比例越来越大。这种情况在热带稀树草原地区更为突出,因为那里通常降雨不足,风化率高。因此,当土壤的养分含量已经足够时,向土壤中添加肥料很可能对土壤和作物都造成损害。因此,在尼日利亚北部稀树草原地区使用有机和无机肥料应根据具体的土壤诊断来确定添加养分的需要。
