“…In spring spinach and mustard planted at BC treatment, total content of free AAs was increased by 7% on average and by 64%, respectively, however not significantly, in comparison to control. Similarly, Younis et al (2015) obtained increasing production of AAs by BC application under toxic levels of Cd and Ni in spinach and fenugreek. According to these authors, high production of AAs and also proteins indicated the activation of defensive mechanism against oxidative damage.…”

Zemanová V., Břendová K., Pavlíková D., Kubátová P., Tlustoš P. (2017): Effect of biochar application on the content of nutrients (Ca, Fe, K, Mg, Na, P) and amino acids in subsequently growing spinach and mustard. Plant Soil Environ., 63: 322-327.The objective of this study was to assess the effect of biochar on growth and metabolism of spinach (Spinacia oleracea L.) and mustard (Sinapis alba L.) planted in crop rotation: spinach (spring)-mustard-spinach (autumn). The impact of biochar soil application (5% per mass of soil) on the availability of Ca, Fe, K, Mg, Na and P to plants as well as the content of free proline and total amino acids contents were evaluated at degraded Chernozem soil. The results showed that biochar soil addition significantly increased spinach growth by 102% and 353% in spring and autumn, respectively. Biochar limited plant content of Ca, Mg and Na, however K content increased in all plants. Inconsistent effect was determined for Fe and P content in plants biomass. Total content of free amino acids was higher in plants harvested at amended treatments, except autumn spinach. Biochar increased proline content in all plants in comparison to control. The highest increase was obtained in mustard -by 186%. The results showed a more sensitive reaction of mustard to biochar application than spinach.

Proline (Pro) is specific free AA which is involved in stress metabolism and tolerance of plants (Pavlíková et al. 2014). Our study aimed to compare the ability of spinach and mustard accumulation of nutrients and amino acids as a response to biochar application to soil. MATERIAL AND METHODSExperimental design and soil characteristics. The experiment was conducted at greenhouse controlled conditions. Spinach (Spinacia oleracea L.) and mustard (Sinapis alba L.) were chosen as experimental plants, while the crop rotation was spinach-mustard-spinach. Firstly, spinach was sown in March and harvested after 64 days. Mustard was sown in May and harvested after 35 days. Late spinach was sown in August, harvested after 64 days. Biomass of both spinaches was sampled once during vegetation, after 42 days. Modal Chernozem soil (2.5 kg; Prague-Suchdol, Czech Republic; pH KCl = 7.2, cation exchange capacity (CEC) = 258 mmol + /kg, C org = 1.83%, available content of elements: Ca = 6754 mg/kg; K = 233 mg/kg; Fe = 153 mg/kg, Mg = 191 mg/kg; P = 74 mg/kg) was uniquely fertilized with 0.1 g N, 0.16 g P and 0.4 g K per 1 kg of soil (applied in the form of NH 4 NO 3 and K 2 HPO 4 ), only at the beginning of the experiment. The experiment consists of 2 treatments: (i) control (without BC) and (ii) 5% of the applied BC from total mass of soil (BC 5%) thoroughly mixed with soil volume.Biochar characteristics. Detailed biochar properties were described in Břendová et al. (2016). Bioc...

“…Pre-experimental analysis of P, K and Ca in BC (Table 1) validated our argument regarding a significant increase in soil EC. A significant amount of presence of mineral nutrients in BC structure is well documented by many scientists 5,34,35 . Abid et al 34 also reported similar kind of significant increase in soil pH when they applied BC in soil under various sources of irrigation.…”

Biochar (BC) is gaining attention day by day due to its potential benefits for the improvement in degraded soil health. During its production by pyrolysis, carbon sequestration is an important aspect that makes it environment-friendly amendment. However, 100% anaerobic combustion of waste at such a high temperature decreases its adaptability to produce Bc at commercial scale. on the other hand, the alkaline nature of BC also causes adverse effects on soil health when used in alkaline soils. Keeping in mind the problem of Bc production and its high pH, current experiment was conducted to introduce chemical production of acidified activated carbon (AAC) and its effects on soil nutrients status comparative to high temperature pyrolyzed Bc. As compared to thermal pyrolysis, sulphuric acid produce acidified activated carbon in minimum time and large in quantity. Sulphuric acid produces acidified activated carbon, fix higher carbon as compared to thermal pyrolyzed BC. Results also showed that application of 2% AAC was far better for decreasing alkaline soil pHs (3.52 and 4.71%) and ECe (45.2 and 71.4%) as compared to control in clay and sandy clay loam. A significant maximum increase in available P (117.5 and 25.9%), extractable Zn (42.0 and 52.2%), B (111.4 and 46.2%) and Fe (59.5 and 34.4%) in clay and sandy clay texture soils also validated the efficacious functioning of AAC over BC and control. it is concluded that sulphuric acid use is an easier and adaptable method to produce activated carbon at commercial scale. As compared to thermal pyrolyzed Bc, application of AAc could be more effective in the improvement of soil health and fertility status. Role of agriculture in food production is immense 1 to fulfil the hunger of human's 2. Today modern agriculture is feeding more than 6000 millions of people, compared to old age hunter-gatherer lifestyle (that provide food to 4 million people) 3. Owing to modern production technologies e.g. use of inorganic fertilizers, pesticides, organic amendments, biofertilizers and genetically modified high yield varieties, the production of crops has become double in the last 40 years 1,4,5. This change in food demand and supply 6 has shifted the conventional agriculture towards the intensive cultivation of crops 7. However, intensive cultivation of crops not only depleted the concentration of the nutrients but also has degraded the soil health. Owing to high soil pH, low organic matter and poor microbial population, now crops are suffering from hidden hunger of macro and micronutrients 5,7,8. To describe such a low concentration of macro and micronutrients bioavailability, poor soil fertility is a general term which is commonly used 9. Since the early years of the 21 st century, the demand and application of inorganic fertilizers were increased tremendously to solve the problem of poor soil fertility 10. It is documented fact that the application of inorganic fertilizers is the necessity of time to get the maximum yield of crops. However, these fertilizers are also costing a lot i...

“…The accumulation of proline has also been observed when plants were exposed to heavy metals (Alia and Saradhi 1991). In a recent study by Younis (Younis et al 2015), spinach (Spinacia oleracea) and fenugreek (Trigonella corniculata) was grown in a Cd-and Ni-contaminated soil treated with 0, 3 and 5% biochar. The authors observed an increase of total amino acid content in the spinach (Spinacia oleracea) and fenugreek (Trigonella corniculata) plants in the presence of biochar.…”

Little is known on the effects of biochar on N uptake and amino acid variability in crops such as winter rye and narrow-leafed lupine despite the fact that amino acids are important indicators, for food quality and plant stress. N uptake of both crops showed contrasting results when treated with different biochar fertilizers. Total amino acid contents referred to total nitrogen generally tend to decrease in rye grains in the presence of biochar; whereas lupine seeds were more or less unaffected by biochar combined with mineral fertilizer or compost. In lupine seeds, total amino acid contents significantly increased when biochar was mixed with digestate but decreased when mixed with fermented digestate. Lysine, one of the most limiting amino acids in cereals, reached the recommended value of 4 g kg −1 in rye grain for most biochar fertilizers. In lupine seeds, lysine decreased when biochar had been applied but were still in the recommended range when used as animal feed. Proline, an indicator for plant stress, significantly decreased (− 49%) in rye when 2 Mg biochar ha −1 was added in combination with mineral fertilizer. In contrast, proline increased when biochar was added to organic (digestate and compost) fertilizers (up to 43%). Further biochar research should focus much more on food quality, which is a key challenge for global food production.
