Positive Effect

It was found that long-term cultivation of perennial cereal bioenergy plants has a positive effect on the fertility of low-yielding soils. Thus, for the cultivation of switchgrass for nine years, the content of organic carbon in the soil increased from 1.87 to 2.40%, and for the cultivation of giant miscanthus for six years from 1.87 to 2.42%. Conclusions. Laying plantations of perennial cereal bioenergy plants on low-yielding and erosion-prone lands helps to restore their fertility and provides a sustainable supply of high quality feedstock for the production of biofuels.

Balanced nutrient supply is important for the sustainable crop production. We evaluated the effects of nutrient management practices on soil properties and crop yields in rice (Oryza sativa L.) - rice - wheat (Triticum aestivum L.) system in a long-term experiment established at National Wheat Research Program (NWRP), Bhairahawa, Nepal. The experiment was designed as a randomized complete block experiment with nine treatments and three replications. Treatments were applied as: T1- no nutrients added, T2- N added; T3- N and P added; T4- N and K added; T5- NPK added at recommended rate for all crops. Similarly, T6- only N added in rice and NPK in wheat at recommended rate; T7- half N; T8- half NP of recommended rate for both crops; and T9- farmyard manure (FYM) @10 Mg ha-1 for all crops in rotation. Results of the study revealed that rice and wheat yields were significantly greater under FYM than all other treatments. Treatments that did not receive P (T2, T3, T7, T8) and K (T2, T4) had considerably low wheat yield than treatments that received NPK (T5) and FYM (T9). The FYM lowered soil pH and improved soil organic matter (SOM), total nitrogen (TN), available phosphorus (P), and exchangeable potassium (K) contents than other treatments. Management practices that ensure nutrient supply can increase crop yield and improve soil fertility status.Int. J. Appl. Sci. Biotechnol. Vol 5(1): 42-50

Наведено результати багаторічних досліджень і узагальнено сучасний стан родючості земель сіль-ськогосподарського призначення Полтавської області. Проаналізовано динаміку забезпечення ґрунтів ґумусом (органічною речовиною) й надані рекомендації щодо подальшого їх призупинення деградації та відновленню. Лабораторними дослі-дженнями протягом 2001–2010 років визначено, що інтенсивна, науково необґрунтована система землеробства призводить до більш високих темпів втрат ґумусу. Вміст ґумусу в області за два останні тури обстеження знизився. За даними VIII туру обстеження, середній вміст його стано-вить 3,39 %, проти 3,26 % у IX турі, тобто змен-шився на 0,13 абсолютних відсотка. Визначено, що навіть за комплексного підходу внесення органіч-них речовин баланс рівноваги елементів живлення в ґрунті порушується. І тільки застосування ком-плексу органічних і мінеральних добрив та наси-чення сівозміни бобовими культурами (соя, горох, багаторічні трави), дотримання науково обґрун-тованої системи землеробства дає змогу підвищити якість земель. The publication presents the results of long-term studies and summarizes the current condition of soil fertility of agricultural land in Poltava Region.  The dynamics of providing soils of the Poltava area with the boron is analyzed and the recommendations in relation to their further stopping degradation and to renewal is given. During 2001–2010 laboratory researches detected, that content of the boron in soils of area for two last rounds of inspection did not change. According to the information of the VIII round of inspection, the average content of the boron is made by 1,05 mgs/kg of soil, against a 1,11 mg/kg in the IX round.

Evaluation soil fertility in dusun kekawii III randotonda Village, Ende District, Ende Regency. This study aims to determine the physical properties of the soil and the level of suitability of the land in Kekawii III hamlet, Randotonda village, Ende District, Ende Regency. Research is exploratory research, by evaluating physical properties, the evaluation results are described and compared with the standard physical properties of existing soil. The results of the study show that the soil properties in Kekawii III Hamlet are the soil texture of the sandy soil, clay. In structures, the types that exist are rounded lumps, lumpy angles, granular structures. On the color of the land dominated by Dark brown, Very dark gray, Very dark grayish brown. The consistency of land, it can be seen that these lands have a consistency that is sticky, plastic, loose, soft. The pH of the soil ranges from 4.2-6.4 and the slope ranges from 5% - 12%
