Low temperature severely depresses the uptake, translocation from the root to the shoot, and metabolism of nitrate and ammonium in thermophilic plants such as cucumber (Cucumis sativus). Plant growth is inhibited accordingly.

High-affinity nitrate transporter 2 (NRT2) genes have been implicated in nitrate absorption and remobilization under nitrogen (N) starvation stress in many plant species, yet little is known about this gene family respond to various stresses often occurs in the production of rapeseed (Brassica napus L.).

Nitrate plays an important role in grapevines vegetative and reproductive development. However, how grapevines uptake, translocate and utilize nitrate and the molecular mechanism still remains to be investigated.

Nitrogen (N) is a major nutrient element for crop growth. In plants, the members of the peptide transporter (PTR) gene family may involve in nitrate uptake and transport. Here, we identified PTR gene family in rice and analyzed their expression profile in near-isogenic lines.

Early seed germination and a functional root system development during establishment are crucial attributes contributing to nutrient competence under marginal nutrient soil conditions. Chenopodium quinoa Willd (Chenopodiaceae) is a rustic crop, able to grow in marginal areas.

Nitrogen use efficiency (NUE) is very important for reducing the cost of production, sustainable agriculture and mitigates the environment pollution. It is more so in case of major cereals like wheat, where the NUE is approximately 40%. NUE comprises of Nuptake by the root and then their assimilation, utilization, remobilization by the shoot. However, utilization primarily dependent on available resources, i.e. amount of N-uptaken by the root system.

In order to grow, plants rely on soil nutrients which can vary both spatially and temporally depending on the environment, the soil type or the microbial activity. An essential nutrient is nitrogen, which is mainly accessible as nitrate and ammonium.

The assessment, presented as ministers met in Amsterdam to discuss greening transport, points out a series of flaws in the tests. First, various equipment that increases vehicle weight, thereby adding to emissions, is not included. Growing use of seat heaters, air conditioning and the like could be adding an extra 16 to 28 grams per kilometer (g/km) to new car CO2 emissions, the agency says.

If the soil becomes saturated, oxygen may become scarce and in anoxic conditions, denitrifying bacteria may convert the nitrate to nitrogen gases (NO, N2O, and N2). Nitrogen converted to these gases becomes unavailable for plant uptake or for surface water contamination. Additionally, saturated soil during the growing season is harmful to many crops like maize that cannot tolerate low oxygen concentrations in the root zone for more than a few days.

Transportation involves the combustion of fossil fuels to produce energy translated into motion. Pollution is created from incomplete carbon reactions, unburned hydrocarbons or other elements present in the fuel or air during combustion. These processes produce pollutants of various species, including carbon monoxide, soot, various gaseous and liquid vapour hydro carbons, oxides of sulphur and nitrogen, sulphate and nitrate particulates, ash and lead.

A ‘textbook’ plant typically comprises about 85% water and 13.5% carbohy- drates. The remaining fraction contains at least 14 mineral elements, without which plants would be unable to complete their life cycles. These essential mineral elements include six macronutrients – N, K, P, S, Mg and Ca – which are present in relatively large amounts in plant tissues (mg g−1 of dry tissue), and several micronutrients, including Fe and Zn, which are present in smaller amounts (µg g−1 of dry tissue).

Standard laboratory methods for measurement of soil nitrate (NO3–N) use various procedures and instruments to analyze soil samples taken from the field and transported to the laboratory. Concerns with these procedures range from delays in measurement time, the high cost of soil sampling and analysis, high labour requirements, and the need to aggregate samples. With recent advances in using the ion-selective electrode, as presented in this chapter, soil NO3–N can now be measured directly, rapidly, accurately, at low cost, at a fine scale, and in real-time right in the field....
