“…In another study in Saskatchewan, nitrate-N in soil was also higher in 6-yr continuous rotations with low crop diversity compared to rotations with high diversity of annual grain crops [21]. Earlier research has also suggested that residual N in soil can be decreased with efficient cropping systems [28]. Similarly, in our study soil nitrate-N in most soil layers was usually lowest in the 3-yr and 4-yr rotations with pea and 4-yr rotation with canola, suggesting the importance of 3-or 4-year rotations in reducing residual nitrate-N in the soil profile.…”

“…OPEN ACCESS high N fertilizer rates [28][29][30] and nitrate leaching in the 90 -240 cm soil profile [21], suggesting the need for deep soil sampling below the 60 or 90 cm depth in future in this long-term study. Soil nitrate-N below the effective root zone of crops is susceptible to leaching, and the loss of nitrate-N through leaching can result in N contamination of groundwater, and thus represents a potential risk to groundwater quality and soil health [31][32].…”

The objective of this study was to determine the impact of frequency of broad-leaf crops canola and pea in various crop rotations on pH, total organic C (TOC), total organic N (TON), light fraction organic C (LFOC) and light fraction organic N (LFON) in the 0 -7.5 and 7.5 -15 cm soil depths in autumn 2009 after 12 years (1998-2009) on a Dark Brown Chernozem (Typic Boroll) loam at Scott, Saskatchewan, Canada. The field experiment contained monoculture canola (herbicide tolerant and blackleg resistant hybrid) and monoculture pea compared with rotations that contained these crops every 2-, 3-, and 4-yr with wheat. There was no effect of crop rotation duration and crop phase on soil pH. Mass of TOC and TON in the 0 -15 cm soil was greater in canola phase than pea phase in the 1-yr (monoculture) and 2-yr crop rotations, while the opposite was true in the 3-yr and 4-yr crop rotations. Mass of TOC and TON (averaged across crop phases) in soil generally increased with increasing crop rotation duration, with the maximum in the 4-yr rotation while no difference in the 1-yr and 2-yr rotations. Mass of LFOC and LFON in soil was greater in canola phase than pea phase in the 1-yr, 2-yr and 3-yr rotations, but the opposite was true in the 4-yr rotation. There was no consistent effect of crop rotation duration on mass of LFOC and LFON. The N balance sheet over the 1998 to 2009 period indicated large amounts of unaccounted N for monoculture pea, suggesting a great potential for N loss from the soil-plant system in this treatment through nitrate leaching and/or denitrification. In conclusion, the findings suggest that the quantity of organic C and N can be maximized by increasing duration of crop rotation and by including hybrid canola in the rotation.

“…Data gathered from farmers' practices (Widowati et al 2012), revealed an average ANUE value 16% for two consecutive years; therefore, more than 80% of N added is susceptible to loss. Application of N fertilizer in excess of crop requirements can result in the accumulation of NO 3 -N in the soil profile (Gillard et al 1995;Malhi et al 2001). Although organic material is considered as a slow-release fertilizer, excessive application may cause unintended NO 3 leaching (Gerke et al 1999) with the percolating water.…”

“…Levels of NO 3 measured in the soil monitored at a depth of 0-25 cm have been found to change very rapidly. Several researchers report an increased concentration of residual NO 3 -N in soil profiles after the application of large amounts of N to different cropping systems (Malhi et al 2001;Gillard et al 1995) and N mineralization from soil organic matter and organic fertilizer, while decreased nitrate content occurs due to plant uptake, immobilization, denitrification, and leaching.…”

High rainfall intensity is major factor governing leaching process, where leaching is often the most important process of N loss from the field and lead to agricultural environmental pollution. In order to measure the movement of mineral-N in soil profile, a field research had been conducted in two sites of center vegetable farming area with six farmer cooperators in Central Java, Indonesia. Regular soil sampling was done from Improve Practice (IP) and Farmer Practice (FP) treatment for three planting seasons during 2007. Almost all treatments FP applied higher rate of N fertilizer compare to IP, but it was not reflected in N profile. Comparison of predicted and measured mineral N content was simulated using Burns  model, then the closeness of the estimation and measured calculated using Coefficient of Residual Mass (CRM) calculation as an indicator with 0 as ideal value. Out of 9 measurements of IP and FP treatment, eight and seven measurements had negative CRM representinga slight overestimation. The NO 3 -N loss estimated using the Burns model for IP and FP was in average of 67% for IP and 71% for FP of total N fertilizer added or 67% for IP and 76% for FP of total-N surplus, respectively. The calculation of potential nitrate concentration (PNC) at 1 m soil depth at the end of the third season showed a high concentration with significant different of IP and FP having mean value of 59.8 and 82.5 mg N L -1 . From the gathered data it was obvious that over N fertilization had negative effect to agricultural environment. Keywords:Farmer practice, improve practice, N loss, over N fertilization Intensitas curah hujan yang tinggi adalah faktor utama yang mendorong terjadinya proses pencucian, dimana pencucian ini adalah proses yang sangat penting terhadap kehilangan N dari lahan dan memicu terjadinya polusi lingkungan pertanian. Dalam upaya untuk mengukur pergerakan mineral N pada profil tanah, penelitian lapang telah dilaksanakan di dua lokasi sentra budidaya sayuran dengan enam petani kooperator di Jawa Tengah, Indonesia. Secara periodik sampling tanah telah dilakukan pada petak perlakuan Improve Practice (IP) dan Farmer Practice (FP) selama tiga musim tanam pada tahun 2007. Hampir semua perlakuan FP mengaplikasikan pemupukan N yang lebih tinggi dibandingkan dengan IP, tetapi tidak terefleksi pada profil N tanah. Perbandingan dari perkiraan dan pengukuran kadar mineral N telah disimulasi menggunakan model Burns , kemudian kedekatan dari estimasi dan pengukuran dihitung menggunakan Coefficient of Residual Mass (CRM) sebagai indicator dengan nilai 0 sebagai nilai ideal. Dari 9 kali pengukuran perlakuan IP dan FP, delapan dan tujuh pengukuran mempunyai nilai CRM negative yang menunjukkan sedikit over estimasi. Kehilangan NO 3 -N yang diestimasi menggunakan model Burns  untuk perlakuan IP dan FP terdapat pada rata-rata 67% untuk IP dan 71% untuk FP dari total pupuk N yang ditambahkan atau 67% dari perlakuan IP dan76% perlakuan FP berdasarkan total surplus N secara berturutan.
