“…Our results provide evidence that composted seaweed can in fact maintain but also moderately enhance soil N storage contributing to long‐term soil quality and fertility without compromising productivity. Roussis et al (2022) found that manure and seaweed compost as opposed to inorganic fertilization had the greatest influence on soil total nitrogen, which was attributed to the clear relationship with the increase in SOM as our results corroborated as well.…”

Algae have an indisputable role in coastal ecosystems, but their accumulation and uncontrolled proliferation cause severe damage for the local municipalities.Fertilization with seaweed has been shown to increase soil fertility and crop production reducing ultimately the need for inorganic fertilizers. However, contradictory results of the compost effect have been reported. In the present work, we aimed at testing the suitability of three composted algae materials obtained in a previous study as soil amendments for vines. The composted materials consisted of pruning waste (P) and seaweed (S) mixed (henceforth, P2S1, P1S1 and P1S2, referring the number to the ratio of P to S). Overall, we observed an increase in soil organic matter, phosphorus (P) and potassium (K) in the soil treated in comparison with soils with inorganic fertilization. A moderate N soil enrichment (ca. 20%) was also detected. The leaf analysis reflected generally the greatest concentrations of NPK for the organic treatments, but this was remarkable only during the first year after seaweed application. A noticeable improvement in grape production was detected especially with the P1S1 compost without compromising grape quality although a decrease in sucrose content was noted with the compost with higher productivity (e.g. P2S1 and P1S1). This slight sucrose drop could be attributable to a greater water availability mediated by the compost or to a dilution factor of the sucrose content caused by a greater number of berries in those vines. These findings suggest that although monitoring of the long-term effects is needed, the use of seaweed amendments for agriculture could offer a costeffective method for coastal municipalities to reduce excessive algae debris while also minimizing the impacts of inorganic fertilization.

“…Appropriate planting density and fertilisation rate are vital for securing a high crop yield and soil carbon (C) accumulation (Xu et al, 2017;Zhao et al, 2021;Roussis et al, 2022). Plant density (PD), an effective agronomic strategy in increasing maize (Zea mays L.) yield, ranged largely among regions and seemed too low.…”

Soil organic carbon (SOC) fractions and soil enzyme activities were effective indicators to represent C changes under different plant densities (PD) and nitrogen (N) application levels, which influenced crop yield in turn. The aim of the experiment was to investigate the impact of PD and N application levels on soil productivity. The experiment conducted in the North China Plain included three plant densities: 1) PD1 -60,000 plants ha −1 , 2) PD2 -67,500 plants ha −1 , and 3) PD3 -75,000 plants ha −1 , and three N application levels: 1) N0 -0 kg ha −1 N, 2) N1 -220 kg ha −1 N, and 3) N2 -290 kg ha −1 N. Maize (Zea mays L.) grain yield was higher when N was applied at the N1 and N2 application levels each year. Obviously, the grain yield and its components at the N1 and N2 application levels showed no difference at each PD, and vice versa. Plant densities and N fertilisation rates significantly affected the content of SOC, microbial biomass C (MBC), and dissolved organic C (DOC). Ranged from 1.85 to 1.98 mg d g −1 , the sucrase activity was larger in the treatment with a high PD and N fertilisation rate. Higher PD yielded the increase of grain yield (GY) by 19.38%, while the kernel number per ear (KN) and the 1,000-kernel weight (TKW) were decreased by 7.81% and 9.03%, respectively. In addition, the grain yield and yield components were dramatically increased at the N2 application level. The SOC content and its fractions and the sucrase activity were also increased with the PD and N fertilisation rate. These results indicated that the optimum PD and N fertilisation rates were benefits for increasing the grain yield and soil C storage. Considering both soil parameters and grain yield, the PD of 75,000 plants ha −1 and the N fertilisation rate of 220 kg ha −1 N were benefits for crop production and soil sustainability.

“…Agronomic nitrogen utilization efficiency is defined as the direct increase in seed output per increased unit of N fertilizer [26]. Physiological nitrogen usage efficiency, on the other hand, is assessed as the nitrogen/carbon balance in the shoots at harvest, which is measured by examining the relationship between the biomass and N content of the shoots [27]. To the best of our knowledge, no evidence exists regarding the impact of nitrogen fertilization on the agro-morphological and yield attributes of S. alba in the Pothwar region of Pakistan.…”

Oilseed crops play a vital role in the economy of Pakistan, yet the production of oilseeds is far less than the demand for them. White mustard (Sinapis alba L.) is an emerging crop, that belongs to the Brassicaceae family. It is considered to be an alternative to all other oilseed crops for dry temperate climates. White mustard develops rapidly, and has a large canopy and deep rooting system; hence, it can draw up nutrients from deeper layers. This study aimed to evaluate the influence of nitrogen on S. alba agro-morphological attributes and enhance nutrient use efficiencies. During the Rabi seasons of 2019-20 and 2020-21, an experiment was conducted at the University Research Farm, Chakwal Road, Rawalpindi. The study included seven treatments, i.e., T1-Control, T2-20, T3-40, T4-60, T5-80, T6-100, and T7-120 kg·ha−1. Each treatment was replicated three times, and the study utilized a randomized complete block design (RCBD). The results revealed that nitrogen at 100 kg·ha−1 was the optimal concentration and significantly increased the agro-morphological parameters, i.e., plant height (47.01%), primary branches (41.36%), secondary branches (45.33%), 1000 seed weight (54.35%), siliques/plant (41.57%), seeds/silique (52.30%) biological yield (68.38%), seed yield (54.90%), harvest index (11%), and oil yield (38.84%), as compared to the control. Moreover, protein contents and oil contents were significantly increased (5.15% and 6%, respectively), as compared to the control, while glucosinolate content was decreased (4.36%). Similarly, maximum agronomic efficiency (AE), apparent recovery efficiency (ARE) (53%), physiological efficiency (PE), and nutrient use efficiency (NUE) were also improved, as compared to the control. Hence, N application at a concentration of 100 kg·ha−1 can be recommended for S. alba under the present cropping system of Pothwar.
